You can stop structured tummy time once your baby is crawling independently, which typically happens between 7 and 10 months. At that point, your baby is naturally spending time on their stomach throughout the day, building the same muscles that tummy time was designed to develop. Until then, tummy time remains one of the most important daily activities for your baby’s physical development.
Why Tummy Time Has an Endpoint
Tummy time exists to solve a specific problem. Since the early 1990s, parents have been advised to place babies on their backs to sleep, which dramatically reduced rates of sudden infant death syndrome. But all that time on their backs meant babies were getting less opportunity to strengthen the muscles in their neck, shoulders, arms, and core. Tummy time fills that gap by giving babies supervised time on their stomachs while awake.
Once a baby starts crawling, rolling freely, and pulling themselves up, they’re doing the work of tummy time on their own. Their neck and trunk muscles are strong enough to hold their head up, push off the floor, and shift their weight. There’s no developmental reason to keep placing them belly-down on a mat when they’re already moving through those positions dozens of times a day by choice.
Milestones That Signal You Can Phase It Out
Rather than picking a specific age, watch for these physical milestones that show your baby has gotten what they need from tummy time:
- Rolling both ways confidently. Your baby can go from back to belly and belly to back without getting stuck. Most babies reach this between 4 and 6 months.
- Pushing up on extended arms. During tummy time, your baby can straighten their arms and lift their chest well off the floor, sometimes looking around the room.
- Crawling or army crawling. Any form of self-directed movement on the belly counts. Some babies skip traditional crawling and scoot, which still means those muscles are engaged.
- Sitting independently. A baby who can sit without support has the core strength that tummy time was building.
Most babies hit all of these milestones somewhere between 7 and 10 months. Some get there earlier, some later. If your baby was premature, adjust your expectations based on their corrected age rather than their birth date.
How Tummy Time Changes as Your Baby Grows
Tummy time at two weeks old looks nothing like tummy time at six months, and understanding how it evolves helps you know what’s appropriate at each stage. In the first few weeks, even one to two minutes at a time counts. The American Academy of Pediatrics recommends starting tummy time from the first day home from the hospital, beginning with short sessions and building up gradually.
By one month, aim for about 10 minutes total spread across the day. By two to three months, most babies can handle longer stretches and may even start to enjoy it as they gain enough neck strength to look around. The general target is to work up to 40 to 60 minutes of total tummy time per day by three to four months, though this doesn’t need to happen in one session. Breaking it into five- or ten-minute chunks after diaper changes or naps works well.
Around four to five months, many babies start rolling during tummy time, which is a sign the activity is doing its job. At this stage, tummy time becomes less of a structured exercise and more of a natural part of floor play. By six months, your baby may prefer being on their stomach and will flip themselves over the moment you lay them down. This transition from “parent-initiated tummy time” to “baby chooses to be on their stomach” is exactly the progression you’re looking for.
What If Your Baby Hates Tummy Time
Many babies protest tummy time, especially before they have the strength to lift their heads comfortably. This is normal and doesn’t mean you should stop early. A few adjustments can help. Lying on your back and placing your baby chest-to-chest on top of you counts as tummy time and is often better tolerated by newborns. Rolling up a small towel and placing it under your baby’s chest gives them a slight boost that makes the position less frustrating. Getting down on the floor at their eye level with a toy or your face gives them something to work toward.
If your baby consistently cannot tolerate any tummy time past three to four months, or seems unable to lift their head at all by two months, bring it up with your pediatrician. Occasionally, difficulty with tummy time signals tightness in the neck muscles (a condition called torticollis) that responds well to gentle stretching or physical therapy when caught early.
What Happens If You Skip Tummy Time
Babies who get very little tummy time tend to hit motor milestones later. They may be slower to roll, sit, and crawl. Research has also linked insufficient tummy time to flat spots on the back of the skull, called positional plagiocephaly, because the baby spends too much time with pressure on the same part of their head.
A 2020 World Health Organization guideline on physical activity for children under five specifically includes tummy time as a recommendation for infants not yet mobile, reinforcing that it plays a measurable role in healthy development. Babies who had regular tummy time showed stronger gross motor skills at six months compared to those who had minimal time on their stomachs.
That said, babies are resilient. If you missed the early weeks or got a late start, beginning tummy time at any point still helps. The muscles respond to the work whenever you introduce it.
After Tummy Time: Keeping Development on Track
Once structured tummy time is behind you, floor play remains important. Babies and toddlers who spend significant time in bouncers, swings, and car seats miss out on the free movement that builds coordination and strength. Letting your baby move freely on a safe floor surface, even after they’ve mastered crawling and walking, continues the physical development that tummy time started.
The transition is simple: you stop placing your baby deliberately on their stomach, and instead give them open space to move however they want. By 9 to 12 months, most babies are so active on their own that tummy time feels like a distant memory.
