Eczema seems to be quite varied between sufferers, so you might find that a cream that works very well for someone else might not have much effect on your DS. I would say keep trying different things until you find something that works. There is another range of products that has been recommended by MNetters, I'll see if I can find a link to it.
Yes ive ordered few products online from your link and your one you talk of .. plus going to ask doctor ... thanks for all your help its so hard to feel your doing the right thing these days .. hv dont really help every other one tells you a different thing .. its so upsetting dont being able to get it right ..
Elena's Nature Collection is the one I was thinking of. I've never tried it because Aveeno works so well for ds, but it has been recommended by several people on MN. Definitely go and see your gp about it. He may prescribe steroid cream as well as moisturisers etc. I don't like using steroid cream on ds, but if he has a flare up it's better to use it for 3 or 4 days than to risk the eczema becoming infected because ds scratches it. I probably only use the steriod cream every 3 months or so, so hopefully it won't have any permanent effect on ds's skin. I hope your ds is feeling much better soon.
It's worth doing a search on eczema, there is lots of good info about it on MN.
I'm still not convinced that you can get the Intense Relief Overnight Aveeno on prescription. Aveeno don't sell it at all in the UK and I'm a bit doubtful that the parmacist would order it from the US for me. I might give it a go if I have to take ds back to the gp.
