Growth spurts and sleep

This guide is general information only and isn't a substitute for medical advice. If you're concerned about your child's health, or they're unwell, please see a doctor.

Your baby has been feeding constantly and sleeping badly for a few days, and someone says "growth spurt". It's a useful shorthand, though it's worth being honest: it's a parenting term rather than a precise clinical one, and it gets blamed for a lot of things it didn't do.

What parents usually mean

A short stretch, often a few days, where a baby seems hungrier than usual, feeds more often, is unsettled, and wakes more overnight. Feeding more frequently for a period is a normal part of the first year, and babies wake at night both to feed and for comfort.

Growth is not steady and smooth, so periods of increased appetite are unsurprising. What is much harder to do is confirm, in the moment, that a given rough patch is definitely a growth spurt rather than a developmental leap, teething, illness, or a habit that has crept in.

How to handle it

It's also worth separating hunger from habit. A baby who feeds briefly and drops straight back to sleep is probably hungry. A baby who takes a few sucks and then wants to stay on you for an hour is more likely using the feed to get back to sleep, which is a different problem with a different fix.

• Feed responsively. If your baby is genuinely hungry, feed them; a few days of extra feeds will not undo your sleep work.
• Hold the routine steady around the extra feeds, so the shape of the day stays recognisable.
• Try not to add new sleep props to get through it, since a few nights of rocking can outlast the spurt that started it.
• Lower the bar elsewhere for the week. Survival is a legitimate strategy.

When it's not a growth spurt

The tell is duration. A genuine feeding-and-unsettled patch usually resolves within days. If it drags on for weeks, something else is going on: a nap transition, a sleep association, a developmental leap, or a feeding issue.

If your baby seems hungry all the time, is unsettled beyond the usual, or you have any concerns about growth, weight gain or feeding, see your GP or child and family health nurse rather than waiting it out.

The honest summary

Growth spurts are a reasonable explanation for a rough few days, and a poor explanation for a rough few months. Use it as a reason to be kind to yourself in the short term, not as a reason to avoid looking at the day's structure if the disruption sticks. Keep sleep safe throughout, in line with Red Nose: back to sleep, own safe sleep space, clear cot.
