Is it Skin Allergy?

There are many babies suffered having red rashes on their skin. I don't know why? One of them is my 4 months old baby boy. I am worried for that. We consult already by the physician. What should I do? Can I treat it by an oinment. The skin of baby is very sensitive so that I can't apply that. #1stimemom #advicepls #theasianparentph #firstbaby
