Tummy Time for Babies: Why It Matters and How to Do It

Since the 1990s "Back to Sleep" campaign dramatically reduced SIDS rates, fewer babies have been spending any time on their stomachs while awake. The result is a generation of babies who need deliberate, regular tummy time to develop the neck, shoulder, and core strength that used to be built naturally throughout the day. It is not optional — tummy time is the foundation every subsequent motor milestone is built on.

Why Tummy Time Matters

The muscles a baby needs to roll, sit, crawl, and walk are all developed from the neck down: neck extensors, shoulder stabilisers, core muscles, and hip extensors. These muscles are only loaded against gravity when a baby is on their stomach. When babies spend their entire awake time on their backs (in a bouncer, swing, car seat, floor), these muscles get very little workout.

The progressive consequences of insufficient tummy time include:

• Delayed head control — which delays everything else
• Flat spots on the skull (positional plagiocephaly) — spending all time on the back concentrates pressure on one area of the still-soft skull
• Delays in rolling, sitting, crawling, and walking — all require the foundation strength tummy time builds

Research comparing motor development across countries shows associations between higher screen or container time (time in bouncers, swings, and car seats) and later achievement of motor milestones.

How to Do Tummy Time: Positions and Techniques

Floor Tummy Time (Classic)

Place baby tummy-down on a firm, flat surface — a play mat or clean carpet. Get down at their eye level. Place interesting objects, a small mirror, or your own face in front of them to motivate head lifting. Avoid supervising from above; the baby needs to lift their head to see you.

• Starting position for newborns: Both arms forward, elbows under shoulders
• For babies who collapse face-flat: Roll a small hand towel and place it under the chest, just below the armpits

Chest-to-Chest Tummy Time

Recline at 30–45° and place baby face-down on your chest. Your face provides motivation to lift their head. This is an excellent option for newborns and for breaking in reluctant tummy-timers. The incline reduces the gravitational challenge slightly, making it achievable for very young babies.

Across-Lap Tummy Time

Sit with your knees together. Lay baby across your thighs, stomach down, with their head slightly lower than the rest of their body (encouraging head-raising). Pat or gently move your leg to provide sensory stimulation. Good for brief post-feed sessions when you need to hold them anyway.

Tummy Time on an Exercise Ball

For babies with good head control (4+ months): firmly hold baby on a small exercise ball in tummy-down position and gently rock. The movement engages core muscles and makes tummy time interactive.

When Babies Hate Tummy Time: Troubleshooting

A baby who cries through tummy time is doing tummy time in the only way they can — fighting through the discomfort of exercises that are genuinely hard for them. The instinct to rescue them from tummy time because they are unhappy has the paradoxical effect of keeping the muscles weak and the task harder for longer.

Strategies that help most:

• Level your face: Get face-down on the floor, 15–30 cm from baby's face. Your face is the strongest motivator.
• Shorten the session: 45–90 second sessions every hour is more effective than one 15-minute struggle.
• Use a mirror: A baby-safe mirror positioned at eye level is reliably captivating.
• Sing: Your voice during tummy time increases tolerance markedly.
• Introduce at the right moment: Alert, recently-changed, 20+ minutes post-feed.
• Start inclined: Chest-to-chest removes some of the gravitational challenge while still building strength.

What Tummy Time Builds: The Motor Progression

When to Flag a Concern

Contact your paediatrician if:

• At 3 months, your baby cannot lift their head off a flat surface at all during tummy time
• At 4 months, they are not spending any weight on their forearms
• At 6 months, they are not reaching for objects during tummy time
• You notice a significant asymmetry — baby consistently turns head only one way (possible torticollis)
• Baby screams through all forms of tummy time even when rested, fed, and awake (possible pain source)

Torticollis — tightness of the neck muscles on one side — causes head-turning preference and is one of the more common causes of tummy time resistance. It is very treatable with physiotherapy when identified early.

The key message: consistent daily tummy time from the first weeks of life, short and frequent, builds the foundation for all gross motor development. It is one of the highest-impact developmental activities in a baby’s first year. For what comes after — rolling, sitting, and first steps — when do babies start walking shows the full progression that tummy time builds toward.
