Sleep changes a lot between the first birthday and the start of school — and keeping up with those changes can feel like a moving target. One week your toddler sleeps beautifully; the next they fight every nap and wake at 5 am. Here is a plain-language guide to how much sleep your toddler actually needs at each age, when nap transitions usually happen, and how to build a routine that works for your family.
How much sleep does a toddler need?
The short answer: 11–14 hours total in a 24-hour period, including naps. That range stays roughly the same from 12 months through age 5, even as the balance between night sleep and nap shifts.
| Age | Total sleep (24 hrs) | Nap pattern |
|---|---|---|
| 12–15 months | 12–14 hours | 1–2 naps (transition period) |
| 15–18 months | 12–14 hours | 1 nap (most by 18 months) |
| 18 months–3 years | 11–14 hours | 1 nap (60–90 minutes) |
| 3–4 years | 10–13 hours | Nap fading; quiet rest still helpful |
| 4–5 years | 10–13 hours | Most have dropped nap; 10–11 hrs at night |
These are ranges, not rigid targets. A child who consistently seems well-rested, wakes up cheerful, and gets through the day without melting down is probably getting enough sleep — even if the numbers look a little different.
The 2-to-1 nap transition (around 12–18 months)
Most babies start the toddler stage on two naps a day. Somewhere between 12 and 18 months — often closer to 15 months — they shift down to one. Signs your toddler might be ready:
- They resist or skip the second nap for several weeks in a row.
- They take ages to fall asleep at the second nap.
- Bedtime is getting harder because they are not tired enough.
The transition usually takes a few weeks and can be bumpy. On the first day of a one-nap schedule, move the single nap to around midday (11:30 am–12:30 pm) and bump bedtime a little earlier — around 6:00–6:30 pm — to prevent overtiredness while your toddler adjusts. An earlier bedtime is not a sign of failure; it is a tool.
You can use our baby sleep schedule tool to generate a custom daily schedule based on your child’s age and wake time.
Sample one-nap schedule (18 months–3 years)
Every family is different, but here is a rough framework that works for many toddlers:
- 7:00 am — Wake up
- 12:00 pm — Nap begins (aim for 60–90 minutes)
- 1:30 pm — Wake from nap (cap nap by 3:00 pm to protect night sleep)
- 7:00–7:30 pm — Bedtime routine begins
- 7:30–8:00 pm — Asleep
If your toddler wakes early (5:30–6:00 am), shift everything earlier. The gap between waking up and starting the nap is usually 4.5–5.5 hours for this age group.
Dropping the nap (ages 3–5)
Most children drop their daytime nap somewhere between 3 and 5 years old. This is a big transition, and it rarely happens overnight.
Signs your child may be ready to drop the nap:
- They consistently take more than 45 minutes to fall asleep at nap time.
- They skip the nap several times a week and still sleep well at night.
- They are tired and grumpy at bedtime when they do nap, because napping pushed them too late.
Even after dropping the nap, a quiet rest period of 30–45 minutes can be a lifesaver — for both of you. Some children will still fall asleep during this time on particularly tiring days. For more detail on this transition, see our guide on dropping the last nap.
Once the nap is gone, bedtime usually needs to move 30–60 minutes earlier to compensate.
Building a calming bedtime routine
A predictable wind-down routine signals to your toddler’s brain that sleep is coming. It does not need to be elaborate — 20 to 30 minutes is plenty. The key is doing the same steps in the same order every night.
A simple routine might look like:
- Bath or face wash
- Pyjamas and nappy change
- Brush teeth
- One or two books in a dim room
- Song or cuddle, then lights out
Keep screens off for at least an hour before bed — the blue light from tablets and phones makes it harder for the brain to wind down. A white-noise machine can help if your home is noisy.
Common sleep disruptions: regressions and what to do
Even with a great routine, sleep will sometimes fall apart. A few common culprits:
- 18-month sleep regression: Often tied to a leap in language and independence. Resist the urge to change everything — extra consistency and patience usually resolves it within 2–4 weeks.
- 2-year sleep regression: Can coincide with a new sibling, starting daycare, or potty training. Maintain the routine as much as possible and offer extra reassurance.
- Night fears (ages 3–5): A normal part of developing imagination. A nightlight, a transitional object (like a stuffed animal), and a calm bedtime check-in can all help.
Temporary disruptions happen. Hold the routine, adjust wake windows and nap timing if needed, and know that things almost always settle back down. If your child’s night wakings are frequent and affecting the whole family, it may be worth talking to your healthcare provider.

A note on early rising
Early waking (before 6:00 am) is one of the most common toddler sleep frustrations. Often the cause is an overtired child going to bed too late — counterintuitive, but true. Try an earlier bedtime for a week before making bigger changes. Blackout blinds can also make a significant difference, especially in summer.
Every child’s sleep needs are slightly different. Trust your read of your child over any chart. If they are growing, happy, and full of energy during the day, they are most likely getting what they need.
Toddler sleep needs don’t shrink — the total hours stay similar; what changes is the nap. If bedtime is a battle, an earlier bedtime (not later) usually helps.
