At night times my son head is very hot and it's sweats is it normal.

A. hi well, it's quiet common for babies to sweat, especially on their heads this happens because their bodies are still regulating temperature and their head are proportionately larger than adults please avoid overdressing as it is most common cause behind this please keep an eye on your child health,if there is symptoms like excess sweating, irritability, fever etc please visit your pediatrician
