What parents should know about plagiocephaly
Plagiocephaly, often called flat head syndrome, occurs when a baby develops a flat area on the back or side of the head. It most often develops during the first months of life, when infants spend much of their time lying on their backs. Pediatricians recommend back sleeping to reduce the risk of sudden infant death syndrome, and this safe sleep practice remains important for infants.
Most cases of positional plagiocephaly are mild. Early awareness can help families understand what to watch for and when it may be helpful to discuss concerns with a pediatrician.
1. It’s a common condition in early infancy
Flat spots can develop when consistent pressure is placed on one area of a baby’s soft skull. Positional plagiocephaly is primarily a head shape difference and does not affect brain growth.
2. Positioning and movement can help reduce pressure on one area
Supervised tummy time, varying how a baby is positioned during play and alternating the direction a baby faces in the crib can help reduce pressure on the same part of the head. These strategies are commonly recommended during early infancy.
3. Evaluation can help determine whether treatment is needed
If a flat spot becomes more noticeable or does not improve over time, a pediatrician or specialist may recommend evaluation. In some cases, repositioning guidance or cranial remolding therapy may be considered to help support head shape development.
UT Health San Antonio’s Cranial Remolding Program provides evaluation and guidance for families with concerns about plagiocephaly and related head shape conditions.
