When Will Your Baby Sleep Through the Night?

Two of my neighbors and my best friend all had babies within just a couple of weeks of each other less than 8 weeks ago. All of them have commented on the sleep deprivation that goes along with having a newborn and one asked me when my babies started sleeping through the night. First, I always need to ask what that means to someone because, for some, they mean to have a baby sleep through the night, including feedings, and others mean sleep straight through 10-12 hours, with no feedings.

What does it mean to have your baby sleep through the night?

For me, “baby sleeping through the night” meant my baby sleeping 10-12 hours without feedings. It was around 4 months old, with both breastfed sons, that they started sleeping pretty much straight through with two feedings at night, so I couldn’t really expect much more than that. Sleep was not perfect (particularly with my eldest son because why else would I have a whole website about baby sleep?), but it was ten times better once I changed their sleep associations with needing to breastfeed to sleep or be rocked to sleep all night long. Of course, that’s the trickiest part of this crazy thing about getting babies to sleep and why it’s never a simple answer or silver bullet (oh how I wish it were! I’d e-mail everyone my silver bullet RIGHT NOW!).

One thing I know for certain is regardless of whether you think of “sleeping through the night” is with or without feedings, it can feel like your baby will never do it. If it’s not one thing it’s another. If it’s not a feeding, replacing a pacifier, or rocking her to sleep, it’s cold in her room. If it’s not cold, maybe it’s hot. If it’s not temperature, your baby is now teething. Later on, with your toddler or preschooler, it might even be night terrors or nightmares. You will think of a million reasons about maybe WHY she isn’t sleeping through the night and you might seriously start feeling like it’s a pipe dream that will ever happen.

When Will Your Baby Sleep Through the Night?

Obviously, I can’t really look into my crystal ball to tell you when YOUR baby will sleep through the night (I save the crystal ball for winning the lottery, but for some reason it’s on the fritz right now), but I can tell you that I’ve heard it all when it comes to doctors telling parents when their baby shouldn’t need anymore night feedings and should be sleeping all night. I can also tell you that parents who are skeptical that their 3-month old breastfed baby can go without any feedings for 12 hours per night, you should be. 12 hours is a LONG time, even for many adults and if your baby is breastfed, she will likely need to eat at night a bit longer than her formula-fed friends.

But, when I hear about 12 to 18-month old toddlers who still need a bottle (or 2 or 3) per night or aren’t sleeping all night, then I say there is action to take IF you want a baby who sleeps through the night. If you are fine with co-sleeping or feeding your toddler at night, then there is nothing much to worry about except the effect on the teeth without brushing and how it can lead to bottle mouth syndrome, in some cases.

The short answer is that NO ONE goes off to college needing a bottle in the middle of the night (at least that I know of), so don’t worry about it “never happening” (same for potty training, by the way, as I never saw anyone in the dorm still wearing diapers).

The not-so-short answer is that if your definition of sleeping through the night is with feedings, your baby can sleep fairly well through the night by 4 to 6 months, usually, on average. If you mean straight through without feedings, most can be night-weaned by around 9 months, sometimes as late as 12 months or beyond. The “experts” all vary:

Dr, Sears (The Baby Sleep Book) says night feedings are normal up through 18 months or more.
Pantley (The No Cry Sleep Solution) agrees.
Weissbluth (Healthy Sleep Habits, Happy Child) says it’s normal for babies to need 1-2 feedings up through 9 months, and can then be night-weaned.
Kim West (Good Night, Sleep Tight) agrees.
Ferber (Solve Your Child’s Sleep Problems) says a baby can go up to 8-10 hours without feeding by 3 months.
Baby Wise agrees.
My pediatrician and yours would probably say something different, too.

This is why reading all of these different opinions made my head spin and I wrote my own book on baby sleep (to save other parents time and money). No, I don’t have THE answer. I actually keep the option open that YOU have the answer! Surprise!

If you think your baby or toddler is waking out of habit, then he probably is. Even if you think he is truly hungry, you might have the confidence that if he would just eat more during the day, he’d be able to sleep all night (I recommend at least an attempt at night-weaning once you feel this way). If you believe your baby or toddler “needs” to eat just to fall asleep and not because he’s hungry, then teach him how to sleep without eating. You know your baby best and the key is not to have the answer (believe me, there is not ONE answer for all of us), the key is to have the tools to teach your baby to sleep independently and when you have your tools, sleeping through the night will naturally follow when your baby is truly ready.

When did your baby/babies sleep through the night?

    My daughter started sleeping 8 hours straight at around 5 1/2 months. My son started sleeping 11 hours at 6 1/2 months. I consider myself lucky in this regard. Napping is another story! 😀

    my daughter slept 10hours straight when she turned 3months and for another 3 months it was bliss! unfortunately at 6mths she got a cold and started waking every few hours. her doc advised me to feed her to settle her again so she gets extra fluids! then teething set in so breastfeeding at these wakings was also to “soothe” my baby. Well now now she is 11months and still waking 2-3 times to feed to complete her 9-10 hours night sleep..Did I spoil her into waking for night feedings? Somehow I feel she really does get hungry as rocking to sleep doesnt help…
    Wonder how long this will last and will she ever go back to sleeping at a stretch

    My first born started sleeping through (i.e. 12 hours without waking at all) at 22.5 months – 3 days before his baby brother was born 5 weeks premature so I count myself lucky that I am not waking with two children now! My first born has always been very small (on the 0.4 percentile or below for weight) and so I continued to breastfeed him at night until he was 17 months when my milk dried up due to my pregnancy. Then I think he woke out of habit for another 5 months or so and just needed reassuring and sometimes a drink of cows milk. It has been a really hard two years in therm so fmy sleep deprivation but he is just such a delightful confident little boy and I am glad I always responded when he needed me. I will definitely be doing some things differently with his baby brother (now 8 weeks) though – i.e. not nursing him to sleep and teaching him to fall asleep on his own in his cot from an earlier age! It can seem like it will never end – I did 5 or 6 times a night for months on end – but it does and I am so proud of my son for how he is sleeping ow. He also does a 2.5 hour nap each day at a regular time which i great for getting things done – I think he is also catching up on sleep from the last 2 years. I guess I will do that once my baby can go a bit longer than 3 hours between feeds!

    It sounds like she now has a sleep association in that she thinks she has to nurse to go back to sleep. This is where you’ll need to come up with a plan or a strategy to help her learn to fall asleep without the nursing. Depending on how much she’s eating during the day, at this age, she really is capable of going through the night with either no feeding or just one feeding which means that now it is just habit for her. I’d recommend reading through this series Nicole wrote about sleep training for ideas and tips on how you can teach her to learn to soothe herself back to sleep when she wakes at night: http://www.babysleepsite.com/sleep-training/sleep-training-from-no-cry-to-cry-series-part-1/

    Hi Laura,
    Good for you! Sounds like you are really in tune with your son’s needs and that he has benefited in the long run for it. Happy to hear that you’ll take what you learned the first time around and apply it to help your younger son to get him on the road to healthy sleep habits as well. Thanks for sharing.
