My 6-year-old used to get a tiny (thumbnail) sized eczema patch if she had too much milk as a baby, but that was about it. She had a inch-square patch on her leg last week, and now has about seven of them (all on the legs). The pharmacist has recommended a simple moisturiser and I am doing oat baths, but I would welcome any advice (or any theories about why this has happened). Diet = same; I changed the washing powder a couple of months ago but we are back on our usual one now; she is not ill. Thank you!
