Broken sleep at 15 months is very common and usually normal — toddlers wake, resist bedtime and need help settling. A calm, consistent routine helps most. Worry is a reason to check, not a diagnosis; see a clinician if sleep problems pair with breathing pauses, daytime exhaustion or developmental delays.

*The nights feel endless when your little one won't settle — but a wakeful 15-month-old is usually a typical toddler, not a warning sign.*

## In short
At 15 months, broken sleep is extremely common and rarely a cause for worry. Many toddlers this age still wake in the night, resist bedtime, or need help settling — this is normal developmental behaviour, not a disorder. Most sleep difficulties at this age respond beautifully to a calm, consistent bedtime routine. Worry on its own is not a diagnosis; it is simply a reason to check in with someone who can reassure you properly.

## What's normal at 15 months
Toddlers this age typically need around **11–14 hours** of sleep across the day and night, including one or two naps. A few things often disturb their sleep — and most are passing phases:

- **Separation awareness** — your toddler now knows when you leave the room, so night-waking and protest at bedtime are common.
- **Teething, growth spurts and milestones** — learning to walk and talk can briefly unsettle sleep.
- **Routine and timing** — a nap that runs too late, an overtired or under-tired child, or an inconsistent bedtime can all make settling harder.
- **Comfort and environment** — hunger, a wet nappy, too much light or noise, or screens before bed.

Gentle, predictable habits help most: the same wind-down each night, a dim and quiet room, a consistent bedtime, and putting your child down drowsy but awake so they learn to settle themselves.

## When to check in
Most of the time, reassurance and a steady routine are enough. Do speak to your paediatrician if you notice **snoring or pauses in breathing**, your child seems excessively sleepy or hard to rouse in the daytime, sleep problems come with poor weight gain, or if night-waking is paired with delays in talking, play or connecting with you. These are reasons for a friendly developmental check — not alarm.

## The Pinnacle way
