Your baby's physical development is unique, and concerns about baby prefers one position (positional preference), here is what you need to know.
The short answer
Many newborns develop a preference for turning their head to one side, which is common and often resolves with simple repositioning strategies. However, a persistent preference may indicate torticollis (tightness in neck muscles), which responds well to stretching exercises and physical therapy when addressed early.
Key takeaways
- Many newborns develop a preference for turning their head to one side, which is common and often resolves with simple repositioning strategies. However, a persistent preference may indicate torticollis (tightness in neck muscles), which responds well to stretching exercises and physical therapy when addressed early.
- Usually normal when: Mild preference for looking one direction that is easily redirected
- Call your doctor if: Baby cannot turn head to one side at all
- 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.”
Parents everywhere have the same worry. You are doing the right thing by looking into it.
What Parents Should Know
According to AAP, NIH guidelines, many newborns develop a preference for turning their head to one side, which is common and often resolves with simple repositioning strategies. However, a persistent preference may indicate torticollis (tightness in neck muscles), which responds well to stretching exercises and physical therapy when addressed early. At 0-1 month, a mild positional preference is very common in newborns and can be related to position in the womb. You may notice baby always turns their head to the same side during sleep, always looks one direction, or seems to have a slightly tilted head. If baby can turn their head both ways when encouraged but prefers one side, this is often a positional preference that can improve with repositioning: alternate the direction baby faces in the crib, alternate which arm you hold baby in during feeding, and provide supervised tummy time to strengthen neck muscles. If baby cannot turn their head to one side, or has a noticeable head tilt, this may be torticollis (tightening of the sternocleidomastoid muscle), which benefits from early evaluation and physical therapy. It is generally considered normal when mild preference for looking one direction that is easily redirected. However, you should contact your pediatrician promptly if baby cannot turn head to one side at all.
Normal vs. Concerning
By Age
What to expect by age
0-1 month
A mild positional preference is very common in newborns and can be related to position in the womb. You may notice baby always turns their head to the same side during sleep, always looks one direction, or seems to have a slightly tilted head. If baby can turn their head both ways when encouraged but prefers one side, this is often a positional preference that can improve with repositioning: alternate the direction baby faces in the crib, alternate which arm you hold baby in during feeding, and provide supervised tummy time to strengthen neck muscles. If baby cannot turn their head to one side, or has a noticeable head tilt, this may be torticollis (tightening of the sternocleidomastoid muscle), which benefits from early evaluation and physical therapy.
1-3 months
Positional preference should be actively addressed to prevent flat spots (positional plagiocephaly). Continue repositioning strategies and increase supervised tummy time. Your pediatrician should assess neck range of motion at well-visits. If torticollis is suspected, early referral to physical therapy leads to the best outcomes. Most cases resolve fully with stretching exercises.
3-6 months
With tummy time, repositioning, and therapy if needed, positional preference typically improves significantly. Baby should have good head control and equal range of motion by 4-6 months. A flat spot from positional preference may still be present but often improves as baby spends more time upright and off the back of the head. Helmet therapy may be discussed for significant cases.
6-12 months
Most positional preferences and torticollis are resolved by this age with appropriate intervention. The head shape continues to improve throughout the first year as baby spends more time upright. Persistent head tilting at this age warrants further evaluation.
What to Tell Your Pediatrician
- Describe when you first noticed baby prefers one position (positional preference) and how it has changed over time.
- Note your baby's current age and which age-specific patterns you are seeing.
- Mention if baby consistently turns head to one side and resists turning the other way.
- Mention if you notice a head tilt or that baby holds their head at an angle.
- 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
- Mild preference for looking one direction that is easily redirected
- Baby can turn head both ways when motivated (following a voice or toy)
- Preference improves with repositioning and tummy time
- Baby consistently turns head to one side and resists turning the other way
- You notice a head tilt or that baby holds their head at an angle
- Baby is developing a flat spot on one side of the head
- Baby cannot turn head to one side at all
- There is a firm lump in the neck muscle
- Head tilt with facial asymmetry or eye alignment concerns
What You Can Do at Home
- Keep track of when you notice baby prefers one position (positional preference) — noting the time of day, duration, and any triggers can help your pediatrician.
- Remember that mild preference for looking one direction that is easily redirected — this is generally within the range of normal.
- At 0-1 month, 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 baby cannot turn head to one side at all.

Preventing Flat Spots on Baby's Head (Plagiocephaly)
Flat spots on a baby's head (positional plagiocephaly) are very common because newborn skulls are soft and malleable. Prevention strategies include regular tummy time when awake, alternating head position during sleep, and minimizing time in car seats and bouncers when not traveling. Most mild flat spots improve on their own as baby grows.
When to Start Tummy Time
Tummy time can and should start from day one. The AAP recommends supervised tummy time from the first day home. For newborns, this can be as simple as placing baby on your chest while you recline, or brief sessions on a firm surface for 1-3 minutes several times a day. Tummy time is essential for developing head control, strengthening muscles, and preventing flat spots.
Supporting Baby's Head and Neck
Supporting your newborn's head and neck is essential because their neck muscles are too weak to hold up their heavy head. Always support the head when holding, carrying, or moving your baby. Most babies develop good head control by 4 months. If your baby's head occasionally flops back briefly, it is very unlikely to cause harm.

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 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.
