Hi, my 4 year old daughter has come up with a rash in the last week. We haven’t used any new soaps/washing powders/changed anything in her diet. It’s over her bottom and legs, the part on her bottom is really itching her, the rest isn’t bothering her. She has come up with a few spots today too. Oilatum isn’t shifting it. I did wonder about eczema but she has never suffered from it previously. Any advice welcome. Thank you.
