Very Humid Hands/Feed resulting in Athlete's Foot

Dear Helen

My 6½ months old son, Mads, has had very humid hands and feet ever since he was born with the result that he now suffers from athlete's feet. He has developed ulceration under his toes with no skin between the toes. He has a bath every 2 days and I change his socks everyday. I always see to it to dry his feet and toes very carefully upon each bath.

My GP has recommended me to use a fungicide, and I wonder whether you may recommend me another kind of treatment?

Best regards
Malene
