Try Eucerin. You can buy it in chemists. It is clinically tested (most skin products are not which is a worry!)… It was recommended to me by a child skin specialist in Crumlins’ Childrens hospital – for my child who had bad excema on her face/arms/legs. This is important – Make sure you buy Eucerin with at least 5% Urea (10% is good too). After a bath – put it on moist skin (just pat dry gently, don’t rub) .. the urea seemingly coats the skin and helps stop moisture escaping. It solved our problem.
Best of luck, its a terrible thing for little ones to suffer from. If you try it , let me know how you get on. Kind regards
ps: my child reacts badly to Johnsons baby products – look at the labels of products (even shampoos) – aveeno is also a Johnsons product – a lot of these products have lots of nice smells in them which actually react to some sensitive young skins..
