DH noticed it first yest when he bathed ds. Ds says it is a bit itchy, but haven't really noticed it bothering him more than that. We thought it might be eczema as he has suffered from this in a minor way for a while, so tried the cream we have for it. But just checked now and quite large blotchy bits seem to be getting worse rather than better. Some bits are puffed up/raised. No change to diet/washing liquid/shower gel. Does any one have any other ideas please?
