The main treatment for athlete's foot is the use of an over the counter antifungal cream, such as Tinactin or Lamisil. Wash and dry the feet thoroughly and then apply the cream to the rash and the surrounding skin twice a day for up to two to three weeks. You should continue the antifungal cream for at least a week after the rash goes away.
Other steps you can take to help prevent athlete's foot is keep the feet dry by encouraging your child to go barefoot or wear sandals, wear cotton socks and change socks twice a day, and dry the feet carefully after showers.
A similar condition that is more common in younger children is juvenile plantar dermatosis, or sweaty socks syndrome.
