What Time Should a Toddler Go to Bed? Sleep by Age

Every parent wants to know: what is a good bedtime for my child? The answer depends entirely on age and wake time. Here’s a breakdown of the AAP’s recommended sleep totals, which power this toddler bedtime calculator:

Age Total Sleep Needed Typical Bedtime
Newborn (0–3 months) 14–17 hours No set bedtime yet
Infant (4–11 months) 12–16 hours 6:30 – 7:30 PM
Toddler (1–2 years) 11–14 hours 7:00 – 8:00 PM
Preschool (3–5 years) 10–13 hours 7:00 – 8:30 PM
School-age (6–12 years) 9–12 hours 8:00 – 9:00 PM

Why Overtired Toddlers Fight Bedtime Harder

The biggest mistake parents make is keeping toddlers up too late hoping they’ll sleep in. Overtired toddlers have more cortisol in their system — the stress hormone — which actually makes it harder to fall asleep and stay asleep. Earlier bedtime almost always means better sleep, not less of it.

Mom tip: If your toddler wakes consistently at 5 AM, try moving bedtime 15–20 minutes earlier for one week. It feels counterintuitive but overtiredness is almost always the cause of early waking.

Signs Your Child Isn’t Getting Enough Sleep

  • Waking up grumpy or crying every morning
  • Falling asleep in the car on short trips
  • Meltdowns in the late afternoon that seem out of proportion
  • Hyperactivity or silliness right at bedtime (this is overtiredness, not readiness)
  • Difficulty waking in the morning or needing to be woken up

Frequently Asked Questions

What time should a 2-year-old go to bed?

Most 2-year-olds do best with a bedtime between 7:00 PM and 8:00 PM depending on their wake time. A child who wakes at 7 AM typically needs to be asleep by 7:30–8:00 PM to get their full 11–14 hours. Use the toddler bedtime calculator above for a precise time based on your child’s schedule.

What time should a 3-year-old go to bed?

Preschoolers aged 3–4 need 10–13 hours of sleep. For a child waking at 7 AM, a bedtime of 7:00–7:30 PM works well. If they’re still napping, you may be able to push bedtime to 8 PM.

When do toddlers drop their nap?

Most children drop their afternoon nap between ages 3 and 4. Signs they’re ready: taking over an hour to fall asleep at nap time, or the nap disrupts night sleep. When they drop it, move bedtime 30 minutes earlier to compensate.
