Toddler Sleep by Age (1–5 Years) | How Much Sleep Toddlers Need

How much sleep toddlers need (1–5 years)

The Australian 24-Hour Movement Guidelines and Sleep Health Foundation recommend 11–14 hours of good-quality sleep in 24 hours for children aged 1–2, and 10–13 hours for children aged 3–5. These figures include naps.

Every child sits somewhere on the range. A well-rested toddler wakes happy most mornings, has predictable moods across the day, and settles to sleep within about 20 minutes. If those markers are missing, sleep totals or timing usually need a tweak.

Typical nap patterns by age

Naps are the piece parents most often ask about — and the piece that shifts fastest.

• 12–15 months: 1–2 naps totalling 2–3 hours; many toddlers transition to a single midday nap during this window.
• 15 months–2.5 years: one midday nap of 1.5–2.5 hours.
• 2.5–3 years: one shorter nap (60–90 min) or beginning to skip.
• 3–4 years: nap gradually drops for most children; expect an earlier bedtime on no-nap days.
• 4–5 years: no nap for most children, replaced by quiet time.

Wake windows and bedtime timing

A wake window is the time your toddler is awake between sleep periods. Windows lengthen with age, and getting them roughly right helps your child fall asleep without a fight.

• 12–18 months: 3–4 hour wake windows; last window before bed 4–5 hours.
• 18 months–3 years: 5–6 hour last window before bed.
• 3–5 years (no nap): 11–13 hour awake stretch, so an earlier bedtime around 6.30–7.30pm.
• Aim for lights out roughly 12 hours before you'd like your child to wake — most Australian toddlers do best asleep by 7–7.30pm.

Signs your toddler is getting the right amount of sleep

Numbers matter less than how your child looks and feels. Use these signals rather than a stopwatch.

• Wakes up naturally most mornings within a predictable window.
• Settles to sleep within 15–20 minutes at bedtime.
• Has energy for play and can cope with normal day-to-day upsets.
• Isn't relying on the car or pram to fall asleep during the day.

Signs your toddler isn't getting enough (or is getting too much)

Under-tired and overtired toddlers can look very similar. Both fight bedtime, both wake early, and both can seem hyperactive at 6pm.

• Not enough sleep: meltdowns from mid-afternoon, second wind at bedtime, early wakes before 6am.
• Too much day sleep: takes over 30 minutes to fall asleep, wakes for long stretches overnight, resists the next day's nap.
• Just right: consistent moods, easy bedtimes, predictable morning wake.

Building a schedule that fits your family

The best schedule is one you can hold Monday to Sunday, not a Pinterest-perfect timetable. Anchor the wake time first, then plan naps and bedtime backwards from it. Small drifts (±30 min) are fine; large swings on weekends are the biggest disruptor of toddler sleep.

Keep meals, outdoor time and the wind-down at similar times each day. Sleep pressure builds most reliably when the daytime rhythm is steady.

Common questions

How much sleep does a 1 year old need?

Australian and international guidelines suggest 11–14 hours of sleep in 24 hours, including naps. Most 12–15 month olds still have 1–2 naps totalling 2–3 hours of day sleep.

How much sleep does a 2 year old need?

About 11–14 hours per 24 hours, usually with one midday nap of around 1.5–2 hours and a bedtime between 7pm and 7.30pm.

How much sleep does a 3 year old need?

Around 10–13 hours per 24 hours. Many 3 year olds still nap but the nap starts to shorten. Bedtime often needs to move 30–60 minutes earlier as the nap drops.

How much sleep does a 4 year old need?

Around 10–13 hours in 24 hours, usually all at night. A 4 year old with a good bedtime around 7pm and a 6.30–7am wake is doing very well.

When do toddlers drop to one nap?

Most toddlers transition from two naps to one between 13 and 18 months. The transition can take 2–4 weeks and often includes some cranky late afternoons — an earlier bedtime helps.

What time should my toddler go to bed?

Most Australian toddlers do best asleep between 7pm and 7.30pm. Work back from your ideal morning wake time — aim for roughly 12 hours in bed at this age.

Is it normal for toddlers to still wake at night?

Yes. Brief wakes are developmentally normal at every age. The question is whether your child can resettle without a long intervention. If not, sleep associations are worth looking at.

My toddler sleeps less than the guidelines — is that a problem?

Not necessarily. If your child is happy, well-behaved and growing well, their sleep needs may sit at the lower end of the range. Chat to your GP or Maternal Health Nurse if you're worried about mood, growth or daytime function.
