When should my child sleep through the night?

Sleep grows the way a child grows — slowly, in its own rhythm, and "through the night" arrives later than most tired parents are led to expect.

In short

Most babies become physiologically capable of sleeping a long stretch — around six to eight hours — somewhere between 4 and 6 months, and many settle into more reliable nights between 6 and 12 months. But brief night wakings are completely normal well into toddlerhood, and "sleeping through" rarely means a flawless, unbroken night. Every child's sleep follows its own developmental clock — slower nights are not a sign that anything is wrong.

What's typical at each stage

• 0–3 months — newborns wake every 2–4 hours to feed, day and night. This is expected and healthy; their tiny tummies and immature body clock simply need it. There is no "sleeping through" to expect yet.
• 4–6 months — the internal day-night rhythm matures, and many babies can manage a 6–8 hour stretch. Night feeds often reduce, though not for every baby.
• 6–12 months — longer, more settled nights become common. Brief wakings still happen — most babies stir between sleep cycles and many resettle themselves.
• Toddlers (1–3 years) — most sleep through, but teething, illness, big developmental leaps and separation worries can bring temporary night waking. This is normal and usually passes.

Gentle, consistent routines help most: a calm wind-down, predictable bedtime, a dark quiet room, and giving your baby a chance to resettle before you step in. Breastfed babies and those who are unwell or going through a growth spurt may wake more — that is not a setback.

When to seek a check

Sleep varies enormously between healthy children, so the pattern matters more than a single number. Consider a developmental check if your child snores loudly, gasps or pauses in breathing during sleep, is extremely difficult to settle every single night well beyond the toddler years, seems excessively sleepy or unrousable in the day, or if disrupted sleep sits alongside concerns about communication, attention or development. These point to looking at the whole picture, not just bedtime.

The Pinnacle way

AbilityScore® is part of Pinnacle’s developmental assessment. Diagnosis, where needed, requires an appropriately qualified healthcare professional — never from an app or online form. If sleep difficulties sit alongside any worry about how your child is growing or communicating, our clinicians look at the whole developmental picture. Explore more on your child's development and how tailored support is shaped through programmes such as occupational therapy when needed.
