Ask any maternal health nurse, midwife or paediatrician what single habit makes the most difference to a baby's head shape — and almost all of them will say tummy time. It's free, it can start on day one, and its benefits go far beyond head shape. Yet it's one of the things parents most commonly under-do, often because their baby resists it and they're not sure how to push through.
Why Does Tummy Time Help with Flat Head?
The connection is straightforward. Babies with positional flat head develop it because of sustained pressure on one area of the skull during rest. Tummy time removes that pressure entirely — while your baby is on their front, the back of the skull is bearing no weight at all.
But tummy time does more than give the skull relief. It also:
- Builds the neck and shoulder muscles that allow babies to hold their head up and turn it freely during sleep — the single most important thing that allows positional flat head to self-correct
- Supports motor development — rolling, crawling, and eventually sitting all depend on the strength built during tummy time
- Develops visual and spatial awareness — the world looks completely different from tummy time, which supports cognitive development
- Reduces overall time in the supine position — even if a baby still favours one side of their head when lying on their back, less total time on their back means less total pressure
Safe sleep reminder: Tummy time is only for supervised awake periods. Always place your baby on their back to sleep — the "back to sleep, tummy to play" guideline remains the safest approach for reducing SIDS risk. Never leave a baby unsupervised during tummy time.
When to Start Tummy Time
From day one — or as soon as you get home from hospital. There's no need to wait. Newborns can have tummy time from birth; the common hesitation around the umbilical cord stump is unnecessary, as tummy time does not disturb the stump.
In the very early days, tummy time can be as simple as placing your newborn chest-to-chest on your own body while you recline. This counts — your baby is on their front, building neck strength, and you're supervising. It's also a lovely bonding activity.
How Much Tummy Time Does My Baby Need?
By around 3 months, the goal is approximately 30 minutes of tummy time spread across the day. Individual babies vary — follow your baby's tolerance and build gradually.
A useful rule: tummy time immediately after a nappy change (when the baby is awake and settled) quickly builds into a habit that accumulates to the daily total without feeling like an additional task.
My Baby Hates Tummy Time — What Do I Do?
This is the most common question parents ask — and it's reassuring to know that almost all babies dislike tummy time initially. Neck muscles are weak, the position is unfamiliar, and the effort required to lift their head feels enormous. The trick is making sessions as positive as possible while still persisting.
Get on Their Level
Lie down on the floor face-to-face with your baby during tummy time. Your face is the most interesting thing in their world — having it directly in front of them is a powerful motivator to lift their head.
Try the Football Hold
Hold your baby face-down along your forearm (the "football hold") while you're seated or walking. This is tummy time without a hard floor, which many babies tolerate better in the early weeks.
Use a Rolled Towel or Small Wedge
Place a small rolled towel under the baby's chest during tummy time. It reduces the effort needed to lift the head initially, making the position more tolerable while still building the right muscles.
Shorter, More Frequent Sessions
If your baby protests after 2 minutes, that's fine — stop, settle them, and try again in 20 minutes. Ten 2-minute sessions is just as good as two 10-minute sessions and far better than skipping it entirely.
Time It Right
Never attempt tummy time when the baby is tired or hungry. Right after a nappy change, mid-morning when they're alert and satisfied — this is when they'll tolerate it best.
Use Interesting Props
High-contrast black and white images, small toys placed just out of reach, or a baby-safe mirror placed in front of the baby during tummy time give them something to look at and work towards.
Is Tummy Time Enough on Its Own?
For mild flat head concerns identified very early, tummy time combined with repositioning during sleep is often sufficient. But for most parents dealing with a noticeable flat spot, tummy time works best as part of a broader approach:
- Tummy time — addresses the root problem (cumulative supine pressure) and builds the strength for self-correction
- Repositioning — alternating head position during rest, encouraging the non-preferred turning direction
- A supportive sleep surface — an ergonomic concave pillow like the Ergo Sleep™ Baby Head Shape Pillow is designed to help distribute head pressure during the hours the baby spends resting
- Medical assessment — to confirm the type and severity of the flattening and check for torticollis or other contributing factors
Think of it this way: tummy time reduces the total supine time. A supportive sleep surface improves the quality of the supine time that remains. Repositioning changes which area of the skull bears pressure. Together, these three address the same root cause from different angles.
What If My Baby Rolls Off Their Tummy?
If your baby rolls from tummy to back during tummy time — congratulations, that's a motor milestone. You can gently roll them back to tummy and continue the session if they seem happy, or treat it as the natural end of that session. Either is fine.
Once babies can roll both ways (typically from around 4–5 months), they can begin to manage their own head position during sleep — which is one of the reasons flat head tends to improve naturally from this age.
What Does Progress Look Like?
In the first weeks, progress in tummy time looks like your baby lifting their head even briefly — a few seconds is a win. By 2 months, most babies can hold their head up for short periods. By 3–4 months, they should be holding the head up well and beginning to look around. By 4–5 months, they may be pushing up on forearms and showing the early signs of rolling.
For head shape specifically: improvement from tummy time and repositioning is gradual and usually most noticeable from around 3–4 months onwards, when the baby gains enough neck strength to reposition their own head during sleep. Keep going even when you can't see immediate change — the cumulative effect of consistent effort over weeks is what matters.
Supporting Your Baby's Head Shape During Rest
Complement your tummy time routine with a breathable, ergonomic support pillow designed to help distribute head pressure during every rest period — cot, pram, car seat and bouncer.
