Yes, while safe back sleeping remains non-negotiable, you can greatly lower the risk of flat spots with daily supervised tummy time and simple repositioning habits. Prevention happens during awake, supervised hours, not at bedtime. Start short tummy-time sessions early, alternate your baby’s head position in the crib, and limit time in car seats and swings. If you notice a strong one-sided preference, or no improvement by 4 to 6 months, call your pediatrician.
TL;DR:
- Regular supervised tummy time of 15 to 30 minutes daily, starting early, helps prevent flat spots by promoting healthy skull pressure distribution.
- Repositioning the baby’s head in the crib and alternating sleep positions each night can significantly reduce sustained pressure on one skull area.
- Limiting extended time in car seats, swings, and bouncers and increasing time on the floor supports healthier skull shape development.
- Physical therapy and repositioning are effective first-line treatments for persistent flat spots, with helmet therapy reserved for severe or unresponsive cases.
- Tracking daily routines, milestones, and repositioning habits simplifies prevention efforts and ensures consistent application of good practices.

Why Flat Spots Form and Who Is Most at Risk
A newborn’s skull is soft and still forming, which makes it moldable under steady pressure. When a baby spends long stretches lying on the same spot, whether in a crib, car seat, or swing, that constant contact can flatten the skull in that area. This is called positional plagiocephaly, and it tends to show up early because the skull is most flexible in the first few months of life.
Prevalence typically peaks around 4 months and often improves by 6 months as babies gain more head control and mobility. Some babies face a higher starting risk than others.
- A natural head-turning preference to one side
- Torticollis, a tightness in the neck muscles that limits turning
- Premature birth, which means more time with a softer skull before full-term muscle strength develops
- Extended hours in car seats, swings, or bouncers
Daily Evidence-Backed Prevention Checklist
Small, consistent habits matter more than one long session of anything. Healthychildren, the American Academy of Pediatrics’ parent resource, recommends supervised tummy time of 15 to 30 minutes a day by around 7 weeks, building toward more as babies grow stronger.
- Start tummy time early and build up. Begin with short, supervised bursts right after birth, then work toward longer stretches as your baby’s neck and shoulder strength improve.
- Rotate sleep position nightly. Alternate which end of the crib your baby’s head faces, and shift the direction they tend to turn toward, so pressure doesn’t land in the same spot every night.
- Limit container time. Car seats, swings, and bouncers are useful for travel and short breaks, but too many hours in them adds up to pressure your baby’s skull doesn’t need. Floor play, with supervision, is a better use of awake time.
- Vary how you hold and feed. Switch sides during feeding and alternate which arm you use to carry your baby. Holding baby upright against your chest or shoulder for a few minutes also gives the back of the head a break from pressure.
- Use babywearing thoughtfully. A front carrier can double as supervised upright time, but never let a baby sleep in positioning pillows, wedges, or other devices marketed for head-shaping. The AAP has warned against these products because they raise suffocation risk without proven benefit.
Pro Tip: Pair tummy time with something your baby already enjoys, like a few minutes of singing or a favorite toy placed just out of reach, so it feels like play rather than a chore.
Copyable Daily Routines by Age
You don’t need a complicated schedule, just a rhythm you can repeat without thinking too hard about it.
- Newborn (0 to 6 weeks): Three to five short tummy-time bursts after feeds or diaper changes, totaling 5 to 10 minutes a day. This builds tolerance before baby can hold their head up well.
- 6 to 8 weeks: Several sessions of 5 to 10 minutes each, working toward 15 to 30 minutes a day. Diaper-change time is a natural trigger since baby is already undressed and on a flat surface.
- 2 to 4 months: Multiple sessions building toward 30 to 60 minutes a day as baby tolerates it, plus a nightly habit of swapping crib orientation.
A 2011 AAP clinical report notes that supervised prone play totaling up to 30 to 60 minutes a day, introduced gradually, supports both motor development and even pressure distribution across the skull.
Busy days don’t need to derail the routine. Stack tummy time onto stroller breaks, right after a nap transition, or during the few minutes before bath time, so it rides along with things you’re already doing.
Red Flags, Treatment Options, and When to Get Help
Most mild flattening resolves on its own as babies become more mobile, but a few signs mean it’s time to loop in your pediatrician rather than wait it out.
- Head asymmetry that persists or worsens at well-child visits
- Signs of torticollis, including a consistent head tilt or limited neck rotation
- No visible improvement by 4 to 6 months despite consistent repositioning
- Any unusual ridging, bulging, or early-fusing soft spot, which could point to craniosynostosis and needs a prompt specialist referral
When a pediatrician flags a concern, the first step is almost always repositioning education paired with physical therapy rather than a jump straight to a helmet. A randomized controlled trial of pediatric physical therapy found that a 4-month program cut the risk of severe deformational plagiocephaly by 46% at 6 months and 57% at 12 months in infants with a positional preference. A broader systematic review and Congress of Neurological Surgeons guideline backs repositioning and physical therapy as first-line care, reserving helmet therapy for moderate to severe cases that don’t respond to conservative treatment. Separate systematic review evidence adds that manual therapy often outperforms repositioning alone, and that parent counseling plays a real role in prevention.
Helmet therapy isn’t a guaranteed upgrade, though. The HEADS randomized controlled trial found no meaningful difference in skull shape at 24 months between helmet-treated infants and those who followed the natural course, while helmets came with higher costs and more side effects. That’s worth knowing before committing to one.
Tracking Makes Prevention Easier to Stick With
A simple log turns good intentions into a habit you can actually see progress on.
- Track daily tummy-time minutes so you can spot whether you’re hitting your age-based target
- Note which way the crib is oriented each night to keep repositioning consistent
- Record any neck stretches or exercises a physical therapist recommends
- Jot down dates for milestones and any torticollis notes to bring to well visits
Having this written down means you’re not relying on memory when your pediatrician asks how things have been going.
A Realistic Note From Rebeka
Most mild flattening improves on its own as babies hit motor milestones, but small, consistent routines genuinely speed that along. Keep back sleeping non-negotiable, build tummy time into your day, and bring your tracking notes to well visits if you notice asymmetry. You’re not failing if your baby needs a little extra help.

Making Room for Prevention in Your Daily Routine
Consistency is the hard part of flat head prevention, not knowledge. A comprehensive planner can include daily prompts, a tummy-time tracker, milestone logs, and quick exercise guides, helping you see at a glance whether you’re hitting your targets without rebuilding a spreadsheet every week.
It’s an organizational aid, not a treatment, but it makes the routines in this guide easier to remember on the days when memory is in short supply. For age-appropriate play ideas that double as awake-time positioning practice, fun activities for older babies are worth bookmarking too. You can explore the full planner at Babybareessentials.

FAQ
Do flat heads in babies go away?
Many mild to moderate flat spots improve on their own once babies start rolling, sitting, and spending less time on their backs, typically by 6 months. Persistent or worsening asymmetry after that point is worth discussing with your pediatrician.
What is the most common cause of a baby’s head being flat?
Consistent pressure on one part of a baby’s still-soft skull, often from always sleeping or resting in the same position, is the most common cause. This is called positional plagiocephaly, and it’s distinct from rarer structural causes like craniosynostosis.
Can holding a baby prevent a flat head?
Alternating which side you hold and feed your baby on, and giving upright chest-to-chest time, helps relieve pressure on the back of the head during awake hours. It works alongside, not instead of, supervised tummy time and crib repositioning.
Can a flat head be corrected naturally?
Many cases improve with consistent repositioning, supervised tummy time, and increased mobility as babies grow. For cases that don’t improve, pediatric physical therapy is typically recommended as a first-line treatment before helmet therapy is considered.
