I had VERY bad eczema when I was a child and was hospitalised regularly, and used steroid creams daily. As a result I know how damaging they are if used over a sustained period of time, so we have for the most part avoided steroids on our daughter.
We follow a fairly complicated and comprehensive routine which is a bit laborious but DOES manage to keep the flare-ups under control.
We only bathe her once or twice a week, and use organic oats wrapped in a muslin cloth in her bath, or Balneum (like Oilatum, but soya oil not petrochemical based).
We use Napier's Infant Starflower Cream (the product page is down at the moment, but here's their main site - www.napiers.net/
all over her body every night, and on her legs (where the eczema is worst) at every nappy change. We have been advised against using petrochemical based creams such as aqueous creams or aveeno as they don't allow the skin to breathe properly. They will have petrolatum in the ingredients list.
We then use (see what I mean by laborious!!) Lavera Baby & Kinder Neutral Protection Cream on the patches of eczema - this cream is a real Godsend! It's been miraculous for us.
We also have to be very careful with animals - we don't have pets at home, but Grandma has 2 dogs, and if our daughter gets too doggy round there her skin flares up. We had 3 cats when I was little, and I'm certain that this made my skin so much worse. I am now VERY allergic to pretty much all animals
!
Diet stuff - cows milk products make her skin flare up, but this is an intolerance rather than an allergy and our paediatrician told us that it wouldn't register on the allergy tests she's had, but to avoid it anyway. We use a combination of sheep milk and Oatly enriched as drinking milk (oats are very beneficial for eczema sufferers) and sheep/goat milk yoghurt and cheeses.
It really is a case of managing eczema rather than curing it, and this can be time consuming and disheartening, but it's worth sticking at it. Trial and error will tell you what works for your child.
Good luck with whatever you decide to try...
(If our daughter's eczema continues to be a problem, we'll take her to see a reputable Chinese Herbal practitioner when she's old enough - expensive, but Traditional Chinese Herbal Medicine got rid of my eczema completely after 19 years of hell!)
