Sleep overview: 18 to 24 months

Whether you’re measuring in the hours she sleeps during the night or her shoe size, which is probably quickly outpacing her age, the signs that Baby is growing up are everywhere. During these months, she may shift towards getting a bit more of her sleep during the night, like the big kids do, and a little less of it during naptime, though naps will probably stay a part of her life for at least another year. This transition isn’t always seamless, but it’s an important step on the journey towards independent, night-long sleep that gives your little one all the rest that she needs to make it through the day.

Sleep at night

In the second half of the second year, toddlers still generally need between 11 and 14 hours of sleep out of every 24 hours, but there’s a good chance that more and more of this sleep is happening at night, and less of it is in the form of daytime naps. Naps might cover 1 to 3 hours of sleep, and most toddlers sleep at least 10 hours a night. In most children, sleep patterns adjust, but general trends about their individual sleep are fairly stable – if your tot has always slept like a brick, for example, her sleep patterns will probably still err on the longer side of normal, while toddlers who have always been light sleepers, and needed less sleep, even from infancy, probably will keep on sleeping lightly and less often than their longer-sleeping peers.

Napping

Suspense, adventure, bloodcurdling shrieks – during the second half of the second year, naptime can have all of the excitement of seeing a thriller on the big screen, and a whole lot less of the quiet comfort of naptime images like counting sheep or visions of sugarplums.

Toddlers in the age range still may be getting as much as 1 to 3 hours of sleep from naps, but it’s often during this time that they start to resist lying down to get some rest, whether that’s at naptime or when it’s time to get ready for bed at the end of the day. Most toddlers are so active and full of energy that it can be tempting to think that they resist naps because they don’t need them anymore, but in many cases, toddlers will resist naptime whether they need it or not, leaving it up to their parents to look for clues about whether they’re ready to graduate to a schedule with one fewer nap in it.

Signs that a toddler might be ready to drop a nap include:

  • She doesn’t just resist taking a nap, but actually has trouble falling asleep at naptime
  • She seems happy and normal for the rest of the day if she misses a nap (if she isn’t ready to drop a nap, she may seem moody, easily frustrated, or just plain tired after missing one)
  • If she starts to have trouble falling asleep at her usual bedtime after she has had a nap

One way many parents find the balance after dropping a nap is by shifting bedtime a few hours earlier to make up the difference.
