my 3 months old boy has developed rashes in his groin, initially it looked like diaper rash and hence we are applying diaper rash cream but now I see blisters are formed. please suggest us whether we need to consult a dermatologist

A. No Need to consult a dermatologist you can consult a paediatrician also it is just an allergy or infection could be fungal infection that is why you can see a little bit of blisters into that area so you get a check with your paediatrician for proper medicine
