Ds1 (9) showed me his feet last night and said "Look at my skin". He has huge flaps of skin peeling off as if he has very bad sunburn(although his feet aren't red!) He said his feet itch slightly.
On one foot it is peeling on his heel and towards the centre of his foot. On the other foot it is central and towards his toes. He is a sweaty boy (lovely) and he does get hot sweaty feet, but that is normally in the warmer months.
Could it be Athlete's foot? I have no idea what that is myself just something I've heard of!
