Tummy time — letting your baby spend short, awake spells on their front — is one of those things you’re told to do without much explanation. It matters because it builds the strength a baby needs to lift their head, roll, and eventually sit, and it helps prevent a flat spot developing on the back of the head from all that (correct and important) back-sleeping. The catch: plenty of newborns hate it at first. Here’s why it’s worth it, how to start gently, how much, and what to do if your baby protests.
Why it matters
Babies sleep on their back, which is exactly right for safe sleep — but it does mean a lot of time with the back of the head resting against a surface. Tummy time is the awake counterweight: time on the front strengthens the neck, shoulders, back, and core, which is the foundation for rolling, sitting, and crawling later. It also reduces the chance of a flat or uneven head shape (positional plagiocephaly).
When and how to start
You can start from the very first days — tiny and gentle. The easiest early version isn’t the floor at all: lay your baby on your chest while you lean back, or across your lap. Being on you absolutely counts, and it’s a gentle introduction.
When they’re ready for more, use a firm, flat surface — a play mat on the floor — for short spells. Get down to their level, talk and make faces, and use a baby mirror or a bold, high-contrast toy to give them a reason to lift their head.
How much
Start with just a minute or two, a few times a day, and build up gradually as they get stronger — short and frequent beats one long session. Always awake and supervised; tummy time is never for sleep, which always happens on the back. A good moment is after a nappy change; avoid it right after a feed, since lying on the tummy can bring milk back up.
If your baby hates it
Very common — and it eases as they get stronger. A few things help:
| If your baby… | Try |
|---|---|
| Fusses straight away | Shorter sessions, stop before the meltdown |
| Hates the floor | Chest-to-chest, or across your lap |
| Flops their head down | A rolled-up towel under the chest for support |
| Gets bored | Get face to face, or use a mirror or bold toy |
Do it when they’re content, not tired or hungry, keep it short and positive, and end on a good note. A little grumbling is part of it; genuine distress means stop and try again later.
A note on head shape
Tummy time is for awake, watched play only. If you notice your baby’s head looks flat or uneven on one side, or they always turn their head the same way, mention it at your routine checks — it’s common and usually improves with more tummy time and by varying their position (alternating which end of the cot they lie at, and which side you carry and feed them on).
The short version
Tummy time is simply the awake partner to back-to-sleep: it builds the strength your baby needs and keeps their head a nice round shape. Start tiny and early — even just on your chest — build up gradually, keep it short, fun, and supervised, and don’t worry about the protests. Every wobbly head-lift is your baby getting stronger, and it’s the start of everything that comes next in their development.
