helio - so sorry for your DS's eczema suffering . I recently discovered that my mother took me to the GP for a diagnosis of eczema at 6 months - made me realise how upset and frustrated she must have been. It made me really sad for her. Have you looked into potential allergens, e.g. milk? Reason I ask is that both DH and I have eczema/ dermatitis, but DS has the world's most beautiful, peachy skin. I didn't have all that much dairy during preg (must cut out all those rich yoghurts now!) and DS's skin was great at birth, then I noticed that his skin started reacting to milk in my diet through BF. I stopped taking milk while BFing, and his skin cleared up. I then later had him tested for milk allergy and bingo! Positive result. So I know the milk upset his skin and it's possible that had I not realised this his skin condition could have worsened and become like mine/ DH's.
I also quaffed loads of fish oils during preg, which is brill for skin (yours too!). Make sure it's fish oils and not fish liver oils, mind, for obvious reasons.
Jojobil - phew! Glad to hear it, girly!
Dalrymps - my GP says that any soap is going to be worse for your eczema than using an oil-based treatment such as the dull as ditchwater emulsifying ointment. I love using nice smellies but for the time being, while my eczema is worse, I'm using emuls (and nice bath soaky-stuff on the occasions when I get a long, relaxing bath). Otherwise if you use soaps, you're damaging the good work being done by your steroids and moisturisers.
As far as absorption of steroid creams is concerned, with dermovate (MumNW - don't worry about using yours once! I've used mine about 8 times, which is okay under supervision) about 10% is absorbed into your bloodstream, so some of that will reach your baby. Then the weaker the steroid, the lower the absorption level.
I bought this moisturiser today and already the worst of my skin feels beautifully moisturised. It's very thick but not oily, and a great intense skin treatment. Also smells nicer than emulsif oint and is a far better moisturiser than...what's that oat-based stuff called again? Aveeno? Aveet?
