Tummy Time for Newborns: When to Start and How Much They Need
Babies used to get their tummy time whether anyone planned it or not. Then the safe sleep guidelines changed, and they didn't.
Back to sleep was the right call — it reduced sudden infant death significantly. The side effect is that babies now spend almost all of their waking time on their backs, which means tummy time has to be deliberate. The muscles that develop face-down don't get much chance otherwise.

What Tummy Time Does
Tummy time builds the neck, shoulder, and core muscles that everything else depends on. Rolling, sitting, crawling, pulling to stand — all of it requires the foundation that time spent prone creates (Hewitt et al., Pediatrics, 2020).
It also prevents positional plagiocephaly — the flattening of one area of the skull that can develop when a baby spends too long in the same back position (Hewitt et al., 2020). A newborn's skull is soft and reshapes under consistent pressure. Tummy time removes that pressure and builds the neck strength to turn the head, which distributes it more evenly.

When to Start
From birth — as soon as you are home from the hospital, whenever the baby is [awake](https://morforbaby.dk/blogs/BLOG/how-much-should-a-newborn-sleep) and supervised. The sessions will be very short at first: a minute or two is enough in the early weeks. The point is not duration but frequency (Helsedirektoratet, Barn under 1 år — fysisk aktivitet).
Short, regular sessions from early on are considerably easier than introducing tummy time at three months to a baby who has never experienced it and has strong opinions about the floor.

How Much Tummy Time
The target is at least 30 minutes across the day, spread over multiple short sessions (Helsedirektoratet, Barn under 1 år — fysisk aktivitet). At one to two months, this might be six sessions of five minutes. By three months, the sessions get longer as neck strength builds and the baby has more to look at.
Thirty minutes accumulates faster than it sounds — every nappy change, every time you put them down after a feed, every carry position face-down along your forearm. It does not have to be formal floor time to count.

How to Do It
On the floor: A firm, flat surface — playmat, blanket on the floor. Get down to their level. In the first few weeks, tummy time on the floor consists largely of the baby pressing their face into the mat and reconsidering all decisions. This is still tummy time.
On your chest: Lie back at a slight angle and place the baby face-down on your chest. This counts. The muscles are working the same way, and the protest is usually lower.
On your lap: Baby face-down across your thighs, head slightly lower than the hips. Good for winding as well. The slight incline makes head lifting a little easier for very young babies.
On your forearm: The classic carry — baby face-down along your forearm, head near your elbow, legs straddling your hand. An excellent option for a grumpy baby. Also counts.
Starting on the chest or lap and gradually moving to the floor tends to go better than starting with the floor and wondering why the baby is furious.

When the Baby Hates It
Most babies hate tummy time initially. This is not a sign that something is wrong — it is a sign that tummy time is hard work and the baby is not used to it yet.
A few things that help:
- Short sessions, more often — two minutes six times a day is better than one ten-minute session that ends in tears
- Get down to their level — a face to look at makes a significant difference; your face in particular
- Use a rolled towel or small cushion — placed under the chest just below the armpits, it gives a slight lift that makes head raising easier in the first weeks
- Tummy time during nappy changes — place them prone briefly before picking up; they're already on the changing mat
- Not right after a feed — face-down on a full stomach is uncomfortable and more likely to end in [spitting up](https://morforbaby.dk/blogs/BLOG/reflux-or-normal-spitting-up)
Tolerance builds as neck strength develops, usually from around six to eight weeks. The sessions that produce genuine outrage at four weeks are usually manageable by eight.

Frequently Asked Questions
When should I start tummy time?
From birth, as soon as you're home from hospital. Start with one to two minutes per session, several times a day, always when the baby is awake and you're present. Build duration gradually from there.
How much tummy time does a newborn need?
Work toward at least 30 minutes across the day by around three months, spread over multiple short sessions. In the early weeks, a few minutes several times a day is plenty.
My baby hates tummy time. What should I do?
Start on your chest rather than the floor — the muscle development is the same and the experience is less alarming. Keep sessions very short and frequent. Get down to their level with a face to look at. Tolerance develops as neck strength builds, typically from around six to eight weeks.
Does tummy time on my chest count?
Yes. Any supervised prone time contributes to the muscle development tummy time is designed to build. Floor time is ideal for strength, but starting on the chest is entirely valid — especially in the early weeks.
Can I do tummy time after a feed?
Wait at least twenty to thirty minutes. Face-down on a full stomach is uncomfortable and increases the chance of spitting up.
