izzy has mild eczema so we have had to be careful what we use, and I feel funny washing her without anything in the water - silly I know when she isnt "dirty" as such but still, so I use products that are all natural like Avado, Gaia and I just picked up some Keri samples at the baby show. I use a bit of baby wash in the bath and a bit on her head and bot to wash her with. Lots of moisturiser for her dry eczemery (heehee) skin and I use Aromababy barrier balm on her bot and at times her eczema and she has never had nappy rash!
