Reasons Toddlers Wake (and Sometimes Cry) At Night

Pin It

maddy dogAlthough we have the strong misconception in our society that babies are supposed to sleep through the night from an early age, luckily there are a lot of people that are aware that until your baby does this on his or her own (and some do it early, but most don’t), it is not a biological normal state of affairs.  They wake for many, many reasons .  However, many of these same people seem to draw the line at toddlerhood.  After all, they aren’t babies anymore and these parents have been promised better sleep as time goes by, right?

“Why is my toddler still waking at night?!”  They demand.

Well, I’m here to offer some answers that focus on the very normal reasons your toddler might be waking (i.e., these are not dealing with health issues that can cause disrupted sleep; if your child has health concerns, please speak to a specialist to determine if these concerns are likely to cause sleep disruptions so you address the underlying issues)…

They want to nurse.  Nursing isn’t only for babies, you know.  Toddlers nurse and toddlers nurse at night, just like they did when they were little.  Granted, night feeds decrease with age and often toddlers are better at the “dream feed” (when they roll over and latch without waking) if you’re bedsharing.  In fact, if you’re following child-led weaning, estimates from cultures around the world where this is the case would suggest a natural weaning time of between 3 and 5 years of age[1] and as such, we can expect some night nursing for these toddlers.

They are hungry.  Even if your toddler isn’t nursing, they are growing at an astounding rate.  Parents often forget that although toddlers are not growing at the rate babies do, it is still far greater than we remember.  In addition, the brain activity at this time is actually greater than that of adults: Toddlers’ brains utilize up to two times the glucose that an adult brain uses, depending on age[2].  How do they get glucose?  Why food of course.  [If you have a toddler who is waking regularly and is complaining of hunger, I would recommend making sure he or she has a high-fat nighttime snack.  Avocado, peanut butter, and high-fat yogurt are all options that may help your child sleep a bit longer before waking.]

They are teething.  Often our babies adjust to teething after the first few teeth come in.  We get complacent as parents because of this and think that the stage “has passed”.  We forget about some of the most painful teeth to come in: Molars.  Molars coming in can disrupt sleep for as long as it takes for them to come down.  There are actually two types of molars: The first often comes in just past a year while the second comes in around two years of age, but can be around age 3 for some kids.  If your child is still nursing, you may expect some increase in nursing, especially at night, but regardless you can probably expect some restless sleep.  Unfortunately your child may not be able to articulate what is bothering them so if you see this behaviour, you may want to keep this in mind.

They need to go to the bathroom.  Toilet learning is commonly done in toddlerhood.  This includes nighttime learning for many kids.  Now, some children will go all night without needing to go to the bathroom, but many won’t.  If you ask around to the adults you know, how many go all night without waking to pee at least once?  I would hazard it’s not a majority.  If our toddlers are well-hydrated, they too will need to pee and will wake.  Some parents get confused because they have their child in a diaper at night, but many toddlers will want out of a wet diaper even at night if they are used to being dry during the day (which we hope they are).  Even if you’re using disposables, some kids will be aware that they peed and want the diaper off, meaning they need to wake to accomplish this.  Regardless, the step forward of having a toddler who is no longer in diapers does mean the possible step back of waking regularly to make sure your toddler hits the toilet (or change the sheets in the case of an accident).  One additional thing is that this can also lead to fitful sleep.  If you find your toddler tossing and turning a lot, this may be a cause and a simple diaper change or trip to the bathroom may be all the fix you need.

They are scared.  More so than babies, toddlers have nightmares.  They get scared of the dark, scared of the loud noises, the shadows, thunder, and more.  In fact, nightmares are more common in children under six than any other age group[3], likely because they have the cognitive awareness to notice a lot about their world without the cognitive capacity to truly integrate all the knowledge needed to put things into context.  This could mean their brain has to process a lot of information, some which may seem scary, at night.  Regardless, lots of parents report nightmares in their toddlers (75% of parents in one study[4]) and the best thing to do is comfort them to get them back to sleep.

They don’t want to sleep alone.  Toddlerhood is also the usual time when a child either (a) transitions to a new bed (crib to toddler bed) or (b) leaves the family bed for his/her own room.  Both of these transitions can lead to changes.  In the first case, as soon as the toddlers can “get out” of the toddler bed (something they presumably couldn’t do in the crib), some parents report their toddler coming into their room almost nightly.  Toddlers that have been in the family bed or room and who are now in their own room may not be ready for this transition and also seek to return to the family bed.  Regardless of the reason, the waking to come to the parental bed is often a sign of separation anxiety, which is quite normal in this age-range[5].  If you can, bear with it to help instill feelings of security.  If you can’t, you can check out these gentle resources.

They are experiencing a cognitive leap.  In line with the increased brain development mentioned in terms of food, there’s also the issue of, well, increased brain development (as there is in infancy as well).  This development leads to what have been termed “cognitive leaps” where we see children experience massive growth in their psychological, cognitive, or social development[6].  Sleep regressions are common during these leaps so parents may experience greater night wakings, nightmares, or separation anxiety.  You can read about many of these leaps here.

They are following our age-old sleeping pattern of two sleeps.  Although we currently live in a society of one, long sleep period, it didn’t used to be like this.  Humans used to regularly have two sleeps, the first 4-5 hours followed by an awake period of 1-2 hours (or longer) then another sleep period or 4-5 hours[7].  I will be the first to accept that this does not work well with our modern day society and structure, but keeping your child in the dark and hoping they go back to sleep isn’t helpful either for a couple reasons.  One, it probably won’t work.  Two, children who spend too long in the dark playing around make associations between bed and play instead of bed and sleep, which we know from work with adults is a problem[8].  If you can roll with it, often these stages pass as our children adjust to our artificial light and longer daytime awake periods, but it can take patience.  You can read one mom’s story about this here.

They just are.  The 3-year longitudinal study by Marsha Weinraub and colleagues[9]  showed us that by a year (the end of “infancy”), over half of children were still waking regularly at night.  Specifically, 67% of kids at 15 months were waking at least 1 night per week (with 12% waking every night), at 24 months, 64% were waking at least 1 night per week (9% waking every night), and at 36 months, 62% were waking at least 1 night per week (6.5% waking every night).  However, the trajectory for a given child isn’t so clear.  These researchers also found that 66% of toddlers were what they called “sleepers”, meaning that the number of wakings they had were steady across the 3 year period; the other 34% were “transitional sleepers”, meaning the children showed a steady decline in wakings over the 3 years.  If you haven’t seen much of a change in your child, it may be this is your child’s sleep pattern (I will discuss gentle options below, stay tuned), but if you’ve seen decreases with time, know that your child is probably heading towards fewer wakings, but just at a slower rate than all those kids other people talk about.  And that’s okay.  Of note is that all the aforementioned reasons will be included in this study, but I’m sure some of these kids just wake because they do.


As with infant sleep, there are some considerations to make here.  If your child is waking in pain—squirming, screaming, etc.—then you need to consider something physically wrong.  The list here, although for infants, is actually applicable to toddlers as well and the possible causes for bad sleep are worth looking into.  The other consideration is that sometimes there may be gentle ways to guide your toddler’s sleep when you know there are no physical or health issues that could be impeding their sleep.  The links at the end of this piece here are great places to start, and there are some suggestions in this series here as well.  However, it is supremely important to mention that, as with infant sleep, having a toddler who wakes is entirely normal.  Your toddler isn’t trying to make you mad or frustrated, so please take a deep breath and respond.

What other reasons have you got for why your toddler wakes?

    Even thought I co sleep and nurse my toddler I love this website because there are times when his sleep has been particularly bad and I wonder if I am doing the right thing. My toddler has always woken every 2-3-4 hours since birth so looks like nothing is going to change in the near future :(
    He is high needs and cannot calm himself on his own. So when he is awake he is awake. That’s one reason why he wakes constantly. His mind is so active even when he sleeps that he wakes and then he is awake and needs help falling back to sleep!

    This is a very timely article! My son is 4 (so not a toddler any more) but comes to our room on average twice a night. He has very real stomach issues which wake him at night, but I should still not let him into our room/ bed because “it will cause so many problems” . Never mind that he is usually in an enormous amount of pain, I should figure out a way to get him from not seeking the comfort of his parents at night. Sticker reward charts and a lock on his door (!) have been the most frequent suggestions. We have been under the care of various pediatric specialists because of very real physical symptoms that accompany this pain but people are still very firm that I shouldn’t respond to him at night because I “need sleep”. We also respond to our healthy daughter at night when she needs/wants us. This article reminds me that at least some people feel like that’s a good thing,so thank you! I do realize this isn’t fully relevant but we’ve been given so much bad sleep advice lately that I needed something like this!

    • says

      I’m so sorry that those are the responses you’re getting! Please know you are 100% doing the right thing for both your children :) I hope his pain subsides soon, but I’m so happy he has you and your partner in the meantime!

    • Nicole says

      I’m so sorry you are going through this! My daughter still has reflux issues at two and still wakes at night. It is so much better though. In the beginning someone gave me a babywise book. hahaha! She could not lay down she was in so much pain. She did not lay down on her own until she was several months old. I understand the bad advice train. Do what you need to do and what you feel is right!! I hope your son gets some relief!

    Hello Tracy, great article, thank you. I wondered about your thoughts on waking or stirring associated with ‘processing what’s been going on during waking hours’? I share a family bed with 3 year old twins and have noticed that the wee small hours are a time when my little fellows will talk about things they found difficult that day, or wordlessly seek the comfort and closeness they need. I am not sure they are always awake – sometimes I just catch enough words to connect the dots to an experience they’ve had. It doesn’t seem exactly like dreaming – the communication is quite concrete and direct – but it isn’t total wakefulness either. Either way a cuddle or dozy chat usually seems to help. This nighttime attentiveness is sometimes a bit tiring for me, and yet I still feel like it’s one of the great advantages of a family bed – that carers can be immediately responsive to this kind of nighttime ‘working through’ of experiences. Do you think this might be something that’s part of the development of little humans (and human parents!) and of the evolution of humans generally?

    • Hannah says

      On reflection, I’d add crying at night to the list too. A better word than processing might also be revisiting. It seems to me that children return to experiences they are trying to make sense of, and the beauty of sleeping beside your child is that you can offer comfort and help when they do – maybe in a way you couldn’t during the day. Everyone gets a second chance to make connections.

      • says

        Actually processing is the best word. There is ample evidence that we consolidate and process daily events during sleep which is why it’s important to sleep well before tests and why lack of sleep can lead to us “forgetting” certain events. The role of sleep in memory and creating schemas is well-known and that extends to toddlerhood. I agree with how nice it is to be there in the bed to help as needed – we do the same thing ourselves :)

    My 4 year old son goes to bed at 630 all the time and always seems to get me up around 11 crying cus he needs a wee but he will go bak to bed his this normal for a 4 year old to do this has he has been out of nappys now since 2 years old and i just cant expain it it like getting up with a bby again my daugter who his 5 i havent had this problem with her

  5. Laura says

    thanks for thr article, it help us to understand better our 2 years daughter. she is waking up between 3 to 4 times at night, and time to time 7 times. we have been co-sleeping and still breast feeding but things are getting worse for me as I am not getting any sleep at all and this sleep drevipration is killing me. I am start to think she has a sleep issue, could be? or a health issue? even so that looks like and she look healthy to me.
    I am consider to night weaning so I could get sleep time to time and she won’t depend of me during the night as much as now. So far I’m frustrated (with my self no being able to cope better) and very tired, I am not function very well during the day and some days I don’t have patience at all, what can I do?

    • says

      I offer consultations if you’re interested in going into more detail – it’s almost impossible to know what to recommend without knowing more details and that takes time to go through.

      I recommend reading ToddlerCalm too though if you’re able to get your hands on a copy!

      • Laura says

        Thanks Tracy for your reply.

        I got ToddlerCalm book – just need the time to read that chapter again… :-)
        And find time to book a consultations, thanks so much.


    • vlrhines says

      I feel for you but rest will come. My question is, how and what is she eating during the day? Now that she is 2, start weaning her off the breast. I hope this helps a bit. If she seems hungry, feed her banana/milk. More info actually needed here to help better.

  6. Louise says

    Hi Tracy, really hoping that you will be able to assist… I have a 2 1/2 year old son and am 7 months pregnant. My son has been waking up every hour at night in a fit of rage which lasts between 5 minutes and 20 minutes. We’ve tried changing his diet because he has a couple of food sensitivities, we’ve tried homeopathic sleep remedies, well – just about everything and nothing seems to help. We really worried about him and would really appreciate any advise for our precious little boy…

      • Reena Philip says

        Hi, I have the same problem as loiuse. I have a 1 1/2 yr old son who has eczema, food allergies, does not eat well, wakes up literally every hour crying and then starts itching. Sometimes its the scratching sound that wakes me up. I give him a shower before bed time and keep moisturizers always handy. He cosleeps with me and when he wakes up he wants to be put to be put to sleep only by me and not by my husband, as soon as he realizes its my husband he cries bitterly though during the day time he plays with him , takes him out for a walk to the park, feeds him but when it comes to going off to sleep he only needs me. after he wakes up I have to rock him to put him back to sleep, which takes sometimes 20-45 mins. In the meantime my husband yells as his sleep is getting frequently disturbed. To add to all this now Im 3 mths pregnant and feel too tired and my back hurts due to frequent waking up and rocking him .Im just so worried thinking about the time when the new born and my elder will be crying together and ill be sitting pulling my hair out. Im so stressed even by the thought of it. I would also like to know should I get my son into the habit of sleeping in his bed so by the time the new born comes he will be independent so i can move my elder one to another room, kindly advise this desperate and frustrated but proud mom

          It sounds like you’ve got a lot going on at the moment. All I can say from this brief bit is that you can absolutely start the process of moving your son to see how it goes. I do offer consultations if you’d like to discuss more in depth what’s going on and what some solutions to the variety of issues might be (except the eczema and medical issues as you need to consult your doctor about that though we can discuss how they influence sleep and crying and other behaviours).

        • Mama says

          Hi, I would suggest cutting out the baths. My 2 year old was having the same problem with eczema and itching at night and my doctor suggested that I try giving her a bath every 3-4 days. This has helped a lot because daily baths can really dry out the skin even more and exacerbate the symptoms caused by eczema. I also would recommend moisturizing your babys skin a couple of times a day.

    What about room temptature. I am lead to believe that toddlers can’t regulate their body temperature as well as adults. As a result if their room is either too cold or too cold, they will wake. Is this true and what are the ideal temptature ranges for toddlers room? Thank you :)

        The ideal varies based on climate – in the summer, you would often go for cooler than you would in the winter, but around 68-70 degrees is cited as being ideal, though that’s too hot for my daughter :)

  8. Katy says

    My almost four year old daughter went for an evaluation with a development paediatrician just a couple days ago. He asked about sleep and I said that we are co-sleeping and that she breastfeeds a few times a night. He then said that he is going to refer me to a social worker to help me get my daughter to sleep without breastfeeding. I already know that I am going to be resistant to any advice this social worker is going to have. What can I do to get them off my back about this?

    Thank you for this article. I am an exhausted mom, but which mom isn’t? Many people have played expert on how my toddler should be put to bed, it’s driving me crazy. I went to a doctor yesterday to check if I had ear infection (I presented the symptoms). And what he did was giving me inappropriate unsolicited parenting advice on how to put my son to bed, by explaining to him that he shouldn’t expect a breastfee and that he must sleep. Gah! explain that to a toddler! And on top of that he was sure I need anti-depressants. Good grief! I should have just gone to a massage therapist that would have cost the same, but I would have been relaxed and gotten some needed sleep instead, and then go home happy to my toddler.
    The fact is I have to trust my gut feelings since I know my son the best. He goes through sleep stages. There were periods when his sleeps were unbroken, but more often than not he wakes up at night although less and less. Nothing that we did or didn’t do change anything. He’s like that. His development is wonderful, ahead in some areas. Plus he is just a very curious little person. So much to process during his night sleep. But although I’ve known that, every now and then I need to stumble upon articles like this that help me get my perspective back. Thank you.

  10. Holly says

    I wanted to thank you for this article. I co-sleep with my 17 month old son and plan to continue to breast feed until he wants to stop. He is a very happy child during the day. He wakes a few times at night, usually to breast feed, but recently he also starts to cry a little as well. I was a little concerned and went online to look up common reasons for this (just to reassure myself that his cries aren’t something I should be overly concerned with). I found a blog on sleep and toddlers and was astounded by its claims that most babies should be able to “sleep through the night by 9 months of age.” Really? The comments by parents and doctors on the blog speak of the kids as if they were pawns: “move them out of the room and they’ll stop crying.” I was so relieved when I found this blog. Reading it brought back my sanity and made me feel that what I am doing is natural and normal. So thank you so much.

      You’re welcome! Sadly our society doesn’t support or acknowledge basic infant biology, instead focusing on pushing infant biology to suit our needs. Hopefully we can see a change in this in our lifetime!!
