my baby is having small small boil on his backside then it converts into very dry skin. it is happening for 4 times till now... what is the cause for this? please suggest me what to do

A. Use a mild cleanser and warm water. After a bath of no more than 15 minutes, rinse completely, gently pat your baby dry and apply a fragrance-free cream or ointment such as petroleum jelly (Vaseline) if no improvement than visit ur doctor
