Hi Op
My 6 up dd has chronic atopic eczema, urticaria and a constant itch to god alone knows what. Once this mess is over push for a referral to a specialist pedeatric dermatology dept. We are under the specialist children's hospital in a local city.
Dd uses hydramol daily as a soap and to combat the worst of the dryness, she is on 30-50 ceterizine daily and still scratches, we use sanex kids for the bath (although the aldi equivalent is just as good) she has double base gel but that is after hundreds of different ones, we have momentasone for breakouts on her trunk and protropic 0.1% for her face. We have been using methotrexate for the past year, and I swear it was drastic but a game changer.
She has had hundreds of allergy reactions to random stuff... She is massively sensitive to citrus... Have a good look at what is on your cleaners etc! She is massively allergic to grass, strawberries, tree sap, plant sap, something in soil, chlorine, some form of pollutant but we don't know what, soap, starch in oats, certain wash powders, Johnsons baby products etc. The list of reactions is endless but all the official tests have not shown a reaction... Although I don't think they worked properly as the metal discs fell off after 15 mins!
They told us not to bath dd too often, but honestly I have gone back to every day because whatever it is in the air has been really bad lately and she has to bathe daily to get it off. She suffers badly with infections in her hands and a form of eczema called herpeticum (related to coldsores) so often has blisters all over her. It is awful. You have my deepest sympathy.
Lots of people recommended the oat baths... My strongest suggestion is don't do it. Maybe try it on a little bit of his skin first, my dd has a huge reaction to the starch etc that was released and her skin literally split open at being touched as a result.
If you want to pm for more details the please feel free, all the creams etc dd is on are only able to be prescribed by a dermatologist not a gp so I would strongly suggest you ask for a referral
