Deformational (or positional) plagiocephaly (DP) is a commonly seen condition, especially since pediatricians began to recommend placing our infants on their backs to sleep. Here’s a study showing that children with DP have lower developmental scores at age 3 compared to those that didn’t have DP. The largest differences were seen in cognition, language, and parent-reported adaptive behavior.
This study doesn’t say anything about sleep positions, but I’m wondering if the children without PD were more likely to sleep on their sides. We know that back sleep, while it can lower your chances of developing sudden infant death syndrome, can potentially lower deep sleep quality, leading to less than optimal brain development.
Dentists are also saying that having an asymmetric or flattened skull in the back can translate to asymmetry of the facial skeletons in the front, leading to TMJ problems and crooked teeth.
How many of you have children that had PD?
