Your baby's physical development is unique, and concerns about only rolls one way, here is what you need to know.
The short answer
It is very common for babies to first learn to roll in one direction and then learn the other direction days or weeks later. Many babies have a preferred rolling direction for several weeks. This usually resolves on its own. However, if your baby can only roll one direction for more than 6-8 weeks, mention it to your pediatrician.
Key takeaways
- It is very common for babies to first learn to roll in one direction and then learn the other direction days or weeks later. Many babies have a preferred rolling direction for several weeks. This usually resolves on its own. However, if your baby can only roll one direction for more than 6-8 weeks, mention it to your pediatrician.
- Usually normal when: Your baby just learned to roll and has been doing it for less than 6 weeks.
- Call your doctor if: Your baby was rolling both ways and has lost the ability to roll one direction.
- Varies by age — see the age-by-age breakdown below
“Supervised tummy time is recommended daily from the time the baby comes home from the hospital to help prevent flat head syndrome and to strengthen neck and shoulder muscles.”
This is one of the most common questions parents ask. Searching for answers means you care.
What Parents Should Know
According to AAP, CDC, NIH guidelines, it is very common for babies to first learn to roll in one direction and then learn the other direction days or weeks later. Many babies have a preferred rolling direction for several weeks. This usually resolves on its own. However, if your baby can only roll one direction for more than 6-8 weeks, mention it to your pediatrician. At 3-5 months, when babies first learn to roll, they almost always roll in one direction first. This is completely normal. Your baby is still figuring out the mechanics and will likely learn the other direction within a few weeks. You can encourage rolling to the non-preferred side by placing interesting toys on that side. It is generally considered normal when your baby just learned to roll and has been doing it for less than 6 weeks. However, you should contact your pediatrician promptly if your baby was rolling both ways and has lost the ability to roll one direction.
Normal vs. Concerning
By Age
What to expect by age
3-5 months
When babies first learn to roll, they almost always roll in one direction first. This is completely normal. Your baby is still figuring out the mechanics and will likely learn the other direction within a few weeks. You can encourage rolling to the non-preferred side by placing interesting toys on that side.
5-7 months
Most babies can roll in both directions by 6-7 months. If your baby strongly prefers one direction but can roll the other way when motivated, this is likely just a preference. If your baby seems unable to roll one direction at all, mention it at your next well visit.
7-9 months
By this age, your baby should be able to roll in both directions. If they still can only roll one way, it is worth checking for asymmetry in muscle tone or strength. Your pediatrician may check for torticollis or other muscle tightness that could make one direction difficult.
9-12 months
If rolling asymmetry persists at this age, evaluation is important. Persistent asymmetry in movement can indicate muscle tone differences that benefit from physical therapy intervention.
What to Tell Your Pediatrician
- Describe when you first noticed only rolls one way and how it has changed over time.
- Note your baby's current age and which age-specific patterns you are seeing.
- Mention if your baby can only roll one direction for more than 6-8 weeks.
- Mention if your baby seems unable rather than unwilling to roll the other direction.
- Let your doctor know if you have noticed any related concerns, such as changes in feeding, sleep, or movement patterns.
- Bring a list of any questions or observations you want to discuss at the appointment.
What Should You Do?
When to take action
- Your baby just learned to roll and has been doing it for less than 6 weeks.
- Your baby can roll both ways but strongly prefers one direction.
- Your baby is under 6 months and developing other motor skills on track.
- You can coax your baby to roll the non-preferred direction with toys.
- Your baby can only roll one direction for more than 6-8 weeks.
- Your baby seems unable rather than unwilling to roll the other direction.
- Your baby has other signs of favoring one side of their body.
- Your baby was rolling both ways and has lost the ability to roll one direction.
- Your baby has sudden weakness on one side of their body.
What You Can Do at Home
- Keep track of when you notice only rolls one way — noting the time of day, duration, and any triggers can help your pediatrician.
- Remember that your baby just learned to roll and has been doing it for less than 6 weeks — this is generally within the range of normal.
- At 3-5 months, focus on observation rather than intervention unless your pediatrician advises otherwise.
- Provide plenty of supervised floor time and tummy time to support your baby's physical development.
- While monitoring at home, seek immediate care if your baby was rolling both ways and has lost the ability to roll one direction.
Related Conditions
My Baby Isn't Rolling Over
Most babies roll between 4 and 6 months, but some perfectly healthy babies don't roll until later - or skip rolling entirely. If your baby is engaging with you, bearing some weight on their arms during tummy time, and meeting other milestones, this is likely just their own timeline.
Baby Torticollis (Head Tilt)
Torticollis is a condition where tightness in one of the neck muscles causes your baby to tilt their head to one side and often prefer looking in one direction. It affects about 1 in 250 infants and is very treatable. Early physical therapy with stretching exercises is highly effective, and most babies recover fully within a few months of consistent treatment.
My Baby Seems to Use One Side More Than the Other
Babies should use both sides of their body fairly equally during the first 18 months of life. While slight preferences can be normal, a consistent pattern of favoring one side - using one arm much more than the other, crawling with one leg dragging, or turning the head predominantly one way - should always be discussed with your pediatrician. Early identification of asymmetry leads to the best outcomes.

Should I Use Adjusted Age for My Preemie's Milestones?
Yes — for premature babies, developmental milestones should be assessed using adjusted (corrected) age, not chronological age, until at least 2 years of age. Adjusted age is calculated by subtracting the number of weeks your baby was born early from their actual age. For example, a 6-month-old born 2 months early would have an adjusted age of 4 months, and should be assessed against 4-month milestones. Most pediatricians use adjusted age for developmental assessment through age 2-3, and for growth charts through age 2.
Baby-Proofing a Small Apartment
Baby-proofing a small apartment is absolutely possible and focuses on the same key safety principles as any home: securing furniture to walls, covering outlets, locking cabinets with hazardous materials, and ensuring safe sleep spaces. Small spaces actually have an advantage - there is less area to monitor. Focus on eliminating the most dangerous hazards first: falls, poisoning, choking, and burns.
My Baby Only Army Crawls
Army crawling (also called commando crawling) is a completely valid and normal way for babies to move. Many babies army crawl for weeks or even months before transitioning to hands-and-knees crawling, and some skip hands-and-knees crawling entirely. What matters is that your baby is independently mobile and exploring their environment.
