Iris, you may already know this but this was what helped to control DS's eczema:
- Eucerin 10% Urea, available from Boots and in prescription. With any other emollient I had to apply it 5-8 times a day, with Eucerin only 3, so it has worked well.
-Aveeno Lotion (without mentol) For DS was almost as good as Eucerin, but has the added bonus that it doesn't sting on broken skin.
-For the bath, oats or Oilatum Plus
-For the itching..... keeping the skin well hidrated. I used to buy the cheapest babygros in ASDA (they are 100% cotton, very soft, not too hot, and cheap enough to ditch them after they get stained with the creams). The idea is to cover child with plenty of emollient, put the babygro on (you can buy a bigger size and sew the end of the sleeves close to prevent them from using their nails), DS managed to wake up with a reasonable hidrated skin). Having said that, one of the most important pieces of advice I was given by the dermatologist was not to make a fuss about it, as stress also make the skin flare, and if covering the hands was causing the baby more stress, well... short nails and to remove covering.
As for nutrition. The important thing is for him to have a portion of protein, and two vegetables/fruits and a portion of carbohidrates per meal. DS lives in pastas and risotos, we change the sauces and ingredients every day to ensure he has enough variety. We also cook the same for all the family which prevent DS having a "water down" version of what we are having, but had the positive effect of enabling us to get to a better diet faster. It seems daunting at the beginning, but once you get the idea of it, and start finding the right replacers, it's actually quite easy.
We are 3 but cook for 5 every night, the extras go into small containers and frozen, ready to be sent to school, nursery or to take with us on days out.
Hope that helps
