Quick answer: most children aged three to five need around ten to thirteen hours in twenty-four, including naps. One to two year olds need roughly eleven to fourteen. Overtiredness in young children looks like hyperactivity, not sleepiness, which is why it so often goes unrecognised.

If we could change one thing in the average family's week, it would not be enrichment or reading practice. It would be an earlier bedtime.

Sleep is where the day gets processed. Memories consolidate, vocabulary settles, the immune system does its maintenance, and growth hormone is released. A tired preschooler is not just grumpy. They are learning less, catching more, and finding self-control much harder.

How much, by age

  • 1 to 2 years: about 11 to 14 hours total, usually including one nap.
  • 3 to 5 years: about 10 to 13 hours total. Many children drop the nap somewhere in this range.
  • 6 years and up: about 9 to 12 hours.

These are ranges, not targets, and children genuinely differ. The better test is how your child is: a well-slept child wakes up mostly by themselves, is reasonable company in the morning, and holds together until lunchtime.

What overtiredness actually looks like

This is the part that catches families out. An overtired young child rarely gets quiet and droopy. They get wired.

Common signs: a burst of frantic energy in the evening, silliness that tips into chaos, meltdowns over tiny things, difficulty settling despite being exhausted, waking very early, and clinginess. Plenty of children who are described as hyperactive at six in the evening are simply past their window.

The counterintuitive fix is usually an earlier bedtime, not a later one. Overtired children sleep worse, not better.

Why bedtime slides late here

Singapore families face a specific set of pressures. Parents get home late, so the only family time available is in the evening. Nobody wants to give that up, and it is completely understandable.

Then there is the afternoon nap at childcare, which for some children pushes the evening later. And there are the enrichment classes stacked after school, dinner at eight, and a child who is still bouncing at half past nine.

A few adjustments help without giving up family time:

  • Move connection earlier where you can. Twenty minutes of full attention at bedtime beats an hour of shared exhaustion at nine.
  • Bring dinner forward, even by half an hour.
  • Look honestly at the nap. If your four-year-old naps for two hours at three in the afternoon and cannot sleep at nine, the nap is the thing to shorten, not the night.
  • Protect one or two evenings a week from anything scheduled.

Building a bedtime that works

Keep it consistent. The same order of events every night. Bath, teeth, pyjamas, two books, song, lights out. Young children have no clock, so the routine is how they know what is coming.

Start earlier than you think. Work backwards from the wake-up time your morning demands.

Dim the lights an hour before. Bright light tells the body it is still daytime.

Screens off well before bed. Both the light and the stimulation delay sleep, and a screen right before bed is the single most common cause of a long settle.

Wind down, not up. Rough and tumble is wonderful, but not at eight o'clock.

Cool and dark. Comfortable temperature, blackout where you can, white noise if the corridor is busy.

Same routine on weekends. Within an hour is fine. A two-hour swing produces a difficult Monday.

The common night-time problems

Endless requests. Water, one more story, another cuddle. Decide in advance what is allowed, deliver it as part of the routine before lights out, and then be warm but boring about extras. Boring is the key word.

Night waking. Very common at this age and usually passes. Keep the response calm, quiet and brief, with as little light and conversation as possible.

Nightmares and night terrors. Nightmares wake the child and they want comfort, so comfort them. Night terrors happen in deep sleep, the child is not really awake and will not remember, so keep them safe and do not try to wake them.

Dropping the nap. Usually somewhere between three and five. Expect a rocky few weeks, and bring bedtime forward while it settles. Quiet time on the bed with books is a good replacement.

The bed leaver. Walk them back calmly and with almost no conversation, as many times as it takes for a few nights. Consistency is what ends it.

What we see in the classroom

Teachers can spot the children who did not sleep, usually before nine in the morning. They are the ones with a shorter fuse, less patience for sharing, and a harder time getting into anything.

It is never a judgement. Evenings are hard and families are stretched. But of all the things parents ask us how to improve, sleep is the one with the biggest effect for the least effort, and it is free.

Shaws Preschool has supported families across the East Coast and Serangoon since 1989 with play-based learning, daily sport and plenty of fresh air, which is excellent for sleep. Come and see a morning: book a tour.
