How much tummy time does my baby need?
What does the evidence say about tummy time guidelines by age during pregnancy?
- Most babies can start tummy time sessions a day or two after they are born. 1
- Babies benefit from having two or three short, 3- to 5-minute tummy time sessions each day, building up so that by about 2 months of age, babies are getting 15 to 30 minutes of total tummy time daily. 1
- Tummy time strengthens a baby's neck, shoulder, and arm muscles to support sitting up, crawling, and eventually walking, improves the baby's ability to move and control their muscles, and is associated with fewer flat spots developing on the back of the head. 1
- Guidance for the 2-month checkup specifically frames tummy time as short periods of supervised playtime, with an explicit caution not to leave the baby alone during it or let the baby sleep on their tummy. 2
- Holding the head up when on the tummy is listed as a movement milestone by 2 months of age, and the general guidance for any missed milestone or parental concern about movement is to act early and talk with the child's doctor rather than wait. 3
- By 5 to 6 months, typical physical development includes being able to push up with the arms while on the tummy to raise the shoulders and head and look around or reach for objects, building on the strength that earlier tummy time sessions develop. 4

Frequently asked questions
When should I start tummy time?
Most babies can start a day or two after birth, with short, supervised sessions while they're awake.
What if my baby hates tummy time and cries?
Keeping sessions short, just 3 to 5 minutes at a time, several times a day, rather than one long stretch, is the starting guidance itself, and you can build duration up gradually as your baby gets more comfortable.
Why does tummy time matter?
It strengthens the neck, shoulder, and arm muscles your baby needs to sit up, crawl, and eventually walk, improves muscle control, and is associated with fewer flat spots developing on the back of the head.
Is it safe to let my baby sleep on their tummy during tummy time?
No. Tummy time is specifically awake, supervised playtime. Guidance is explicit that you shouldn't leave your baby alone during it or let them fall asleep on their stomach.
Does tummy time relate to my baby's head shape?
Yes, it's one of its named benefits: spending awake time off the back of the head is associated with fewer flat spots developing there, alongside the muscle-strengthening benefits.
What if my baby isn't holding their head up during tummy time by 2 months?
Holding the head up during tummy time is listed as a 2-month movement milestone. The general guidance for any missed milestone or a concern you have about movement is to act early and talk with your baby's doctor rather than wait and see.
When can I stop doing dedicated tummy time?
There's no fixed end date in the guidance. It folds into general playtime as strength builds, and by around 5 to 6 months many babies are pushing up on their arms and moving more on their own, a sign of the strength these sessions were building toward.
