Quick answers

Frequently asked questions

When do babies sleep through the night?

It varies a lot. Many babies start sleeping longer stretches somewhere between 3 and 6 months, but plenty take longer, and that's normal. Our guide on newborn sleep walks through what to expect by age.

What is a sleep regression?

A few days to a few weeks of broken sleep, often around a new skill like rolling or crawling. It usually settles on its own. Keep the routine steady and offer extra comfort.

How long should wake windows be?

They grow with age, from under an hour for newborns to several hours for toddlers. See our wake windows by age chart for typical ranges.

Is a sleep sack safe for my baby?

A wearable blanket keeps loose bedding out of the crib, in line with AAP safe-sleep guidance: baby alone, on their back, on a firm, flat surface. Pick the size for their current weight and dress for the room temperature.
