Plagiocephaly: Flat Head Syndrome Explained (and When to Seek Help)
Flat spots on a baby’s head are incredibly common — but knowing what’s normal and when to seek support can feel confusing for parents.
What is plagiocephaly?
Plagiocephaly refers to asymmetrical flattening of a baby’s head, often noticed in the first few months of life.
What causes it?
Head position preferences
Body tension or torticollis
Limited tummy time tolerance
Prolonged time in containers (car seats, swings, loungers)
Does it affect development?
Head shape itself doesn’t equal delayed development, but the movement restrictions causing it might.
How PT helps (and when helmets are considered)
Physical therapy addresses the root cause:
Neck mobility
Body symmetry
Strength and motor skills
Parent education for positioning
Many babies improve significantly with PT alone — helmets are only recommended in specific cases.
If you’re worried about your baby’s head shape, early evaluation brings clarity and peace of mind. Always here to help you, mama!
