Many Thanks for the advice. We were referred to Child Dermatology who could';t get to the bottom of it after a few sessions. They then referred us to Child Psychology who very quickly agreed that my daughter is a happy and content little girl. We've been through this cycle (Doctor>Child Dermatology>Child Psychology) twice now and still no further on really, although I realise that everybody in the medical profession has tried their best. The marks seem to come up every 2 - 3 months but we cannot put our finger on anything (food, environment, activity at the time etc.) which may be the trigger. Do you happen to recall the name of this Specialist please? I'd be very keen to contact contact this individual. Many Thanks again for the reply - very much appreciated.
