Tummy time is simply placing your baby on their stomach while they’re awake and you’re watching them. It’s one of the earliest forms of exercise for newborns, building the neck, shoulder, and back strength they’ll need to eventually roll over, sit up, and crawl. Babies can start tummy time from their very first days home from the hospital, beginning with just a few minutes at a time.
Why Tummy Time Matters
Since babies sleep on their backs (the safest position for reducing SIDS risk), they spend a lot of hours with the back of their head pressing against a flat surface. Without regular time on their stomachs, that constant pressure can create flat spots on the skull, a condition called positional plagiocephaly. The National Institutes of Health specifically recommends regular, frequent tummy time sessions to prevent these flat spots.
But head shape is only part of the picture. When a baby lies on their stomach, gravity forces them to work. Lifting their head strengthens neck muscles. Pushing up on their arms builds shoulder and chest strength. Shifting their weight from side to side develops the core stability that eventually makes rolling, sitting, and crawling possible. Babies who get consistent tummy time tend to hit these gross motor milestones on a more predictable schedule.
When to Start and How Long to Go
You can start tummy time as soon as you bring your baby home. In the first few weeks, sessions only need to last one to two minutes. Most newborns will fuss quickly, and that’s completely normal. The goal at this stage isn’t duration but frequency: aim for several short sessions spread throughout the day, such as after each diaper change.
As your baby gets stronger, gradually increase session length. By two months, many babies can tolerate longer stretches and will begin lifting their head to about a 45-degree angle, with their chest slightly coming off the ground. By three to four months, most babies are working toward a combined total of 20 to 30 minutes of tummy time per day, broken into multiple sessions. By five or six months, many babies actually enjoy being on their stomachs and will start reaching for toys, pivoting in circles, or rocking on their hands and knees.
Five Positions Beyond the Floor
Floor time on a blanket is the classic approach, but it’s far from the only option. Mixing up positions keeps your baby engaged and lets you fit tummy time into different moments of the day.
- Tummy to tummy: Sit with your back supported and lay your baby face-down on your chest. They’ll naturally try to lift their head to look at your face, which is one of the best motivators for a newborn.
- Over your lap: Place your baby stomach-down across your thighs while you’re sitting. Keep a hand on their back or hips so they feel secure. This works especially well if getting up and down from the floor is difficult for you.
- Tummy down carry: Hold your baby along your forearm with their belly facing down, supporting their head with your hand. As they get stronger, shift your support to their body so they practice holding their head up on their own.
- Over your leg: While sitting on the floor, drape your baby over one outstretched leg. The slight elevation makes it easier for them to lift their head and bring their arms forward.
- On a wedge or rolled towel: Placing a small rolled towel or nursing pillow under your baby’s chest creates a gentle incline. This reduces the effort needed to lift their head and is especially helpful for babies who struggle with flat-on-the-floor positioning.
What to Do When Your Baby Hates It
Most babies protest tummy time at some point, especially in the first few weeks. Their head is heavy relative to their body, and the position is genuinely hard work. Fussing doesn’t mean you should stop altogether. It means you should adjust.
Start with chest-to-chest positions, where your face provides comfort and motivation. Place high-contrast black and white toys or a small mirror in front of your baby to grab their attention. If your baby is struggling to lift their head, try gently pressing down on the back of their pelvis (over their bottom). This shifts weight away from their chest and makes head lifting easier. You can also try the “super baby” hold: support your baby face-down along your forearm and carry them around the house, letting them look out windows or see themselves in mirrors. This counts as tummy time and many babies who hate the floor love being on the move.
The key principle is short and frequent. Two minutes five times a day is far more productive than one miserable ten-minute session. End each session before your baby gets truly upset, so they don’t start associating stomach time with distress.
Babies With Reflux
Babies who frequently spit up after feeding often have a particularly hard time tolerating tummy time. Pressure on a full stomach can make reflux worse and the experience unpleasant. The simplest fix is timing: wait at least 20 to 30 minutes after a feeding before starting a session.
Position matters too. Laying your baby over your leg or on a wedge keeps their head higher than their stomach, which reduces the likelihood of spit-up. These inclined positions also keep the baby’s back in a more relaxed posture, making the whole experience more comfortable. If reflux is severe, your pediatrician can help you find a schedule and set of positions that work for your baby specifically.
Milestones to Watch For
Tummy time progress follows a fairly predictable pattern. In the first month, your baby may only turn their head to one side and barely lift it off the surface. By two months, most babies can raise their head to a 45-degree angle and hold it briefly. Between three and four months, you’ll see them pushing up on their forearms, looking around, and holding their head steady for longer stretches.
Around four to five months, many babies begin pushing up on straight arms, reaching for nearby toys with one hand while supporting themselves with the other. By six months, some are pivoting in a circle on their bellies or rocking on their hands and knees, the precursor to crawling. Every baby develops at their own pace, but if your baby isn’t lifting their head at all by two months or shows a strong preference for turning to only one side, it’s worth bringing up at your next well-child visit.
Safety Basics
Tummy time always means awake and supervised. A baby who falls asleep on their stomach should be gently rolled onto their back. Use a firm, flat surface like a play mat or blanket on the floor, not a couch, bed, or soft cushion where a baby could sink into the material. Keep small objects and loose blankets out of reach. And while tummy time is essential during waking hours, it doesn’t change the rule for sleep: babies sleep safest on their backs, on a firm surface, with nothing else in the crib.
