Hi there Mulga.
Hi there. As your child is 3 1/2 years old, it is best he be seen by a dermatologist
nearest you for best results. I dont advocate playing the guessing game or online consultations for kids.
However, should you be far away & unable to reach a hospital, please do take a good cleardigital photograph of said lesions & use our premiun 'ask-a-specialist' feature to get in touch with me privately on this portal to take this further.
Off the cuff, i would recommend a neutral cleanser like cetaphil
from galderma & topical miconazole
cream applied locally twice/day for 3-5 days. If absolutely no response, then time for tubby bye-bye & please go visit your friendly neighbourhood dermatologist!
Cheers & wish you both a healthy skin & good luck!
