My baby has a rash on his body in two or three places. What is the reason for this? When he was born, they said that he had sensitive skin and introduced soap and lotion for it. I used that and then after 9 months I started using powder for him. So far, there has been no problem. He has had this rash on his body for at least a week. What should I do? they prefer dermadew lotion again may use this product for my baby.
