Sleep at 3 years: what’s normal, what’s hard, and when to get help

From age 3, the AASM recommends 10 to 13 hours of sleep per 24 hours, including naps. About a third of children have stopped napping by their third birthday, and most of the rest stop over the next two years. Bedtime negotiation, fears and early waking are common. Regular snoring is worth raising with your pediatrician because sleep apnea affects an estimated 2% of children.

What is changing at 3

By 3 years, the CDC lists holding a conversation with at least two back-and-forth exchanges, asking who, what, where and why questions, joining other children to play, and calming down within 10 minutes after you leave, such as at a childcare drop-off. Your child can now argue about bedtime fluently.

The AASM range drops at the third birthday: 10 to 13 hours for 3 to 5 year olds, compared with 11 to 14 hours for 1 to 2 year olds. In a review of studies, children aged 2 to 3 averaged 12.0 hours per 24 hours. Night terrors remain common at this age, according to the AAP, and usually happen early in the night.

Napping at 3 and after	What the research shows (Staton 2020)
Stopped napping by age 3	About 33%
Stopped by age 3 to 4	About 57%
Stopped by age 4 to 5	About 80%
Average nap, ages 3 to 4, among nappers	About 1.7 hours

If your 3 year old still naps and falls asleep at a reasonable bedtime, there is no reason to stop. If the nap pushes bedtime late night after night, what to do about it depends on your child.

At 3, a plan works through rules your child can understand and predict, held the same way by every adult. Actually Sleeping works with babies and toddlers from newborn on: Dr. Sam writes the plan for your child, with bootcamp-style coaching before night one and daily 1:1 check-ins.

What parents find hardest

Negotiating. Requests, questions and “one more” at bedtime.
Coming out of the room, again and again.
Fears and nightmares. The AAP says nightmares peak between 3 and 12 years and happen in the second half of the night. Go quickly, comfort, and encourage sleep.
Dropping the nap. The in-between months, when some days need a nap and some do not, are often the hardest.

Sleep and safety at 3

Keep the bedroom safe for a child who wanders: anchored furniture, a gate at the top of the stairs, window guards above the first floor (AAP).
Stop screens 1 hour before bedtime and keep the bedroom media-free (AAP).
Cap entertainment screen time at 1 hour a day through age 5 (AAP).

Night waking and milk

Most 3 year olds do not need to eat at night, but if your child still wakes for milk, check with your pediatrician before changing it. Brush teeth after the last milk of the day.

When to talk to the pediatrician

Frequent snoring, problems breathing at night, daytime sleepiness, trouble paying attention or behavior problems. The AAP lists these as signs of sleep apnea and estimates it affects about 2% of children.
Night terrors that keep happening.
Sleep that is very short, very restless, or suddenly worse alongside other changes.
Your child is hard to understand most of the time or is not joining in play with other children.

Where to go from here

Most families who come to us with a 3 year old have already tried things on their own. What usually changes things is a plan built for that child and support while it runs. Actually Sleeping provides both, with the written guarantee: We guarantee that your baby will sleep 8–12 hours through the night within 14 days of consistent, correct implementation of your sleep plan. Parents describe the experience on our 12 months and up reviews. Related: a toddler who will not stay in bed, false starts at bedtime, and early waking.

Frequently asked

How much sleep does a 3 year old need?

The AASM recommends 10 to 13 hours per 24 hours, including naps, for children 3 to 5 years old, and the AAP supports this range. Your child may sit anywhere in that range and be well rested.

Should my 3 year old still nap?

Many do. A systematic review found about a third of children have stopped napping by age 3 and about 57% by age 3 to 4. If the nap does not push bedtime late, there is no reason to stop it. If it does, the right change depends on your child.

Is snoring in a 3 year old a problem?

Occasional snoring with a cold is common. Frequent snoring, breathing problems at night, daytime sleepiness, trouble paying attention or behavior problems are signs of sleep apnea, which the AAP estimates affects about 2% of children. Tell your pediatrician.
