any idea?advice?

I would just see how things go when he gets here. Then if you do notice him starting to get some eczema, try and work out the triggers. Be careful with what creams, bath washes etc you use as many of the supermarket ones will totally dry out their skin. They dont really need anything in their bath anyway. If you are worried about the food issues, try delaying solids until 6 months if you can and only introduce low allergen foods, and iintroduce everything slowly so if you do get some kind of reaction you know what it was from. HTH.

Yep just introduce one new food at a time,...like per week, so you will see if he is going to get a delayed reaction,..like excema a few days after its introduced. I guess thats a way off yet tho!
I avoided all nuts when ttc/preg/bf to try prevent allergies as I have always had mild asthma, hayfever and occasional food related hives. But unfortuatley Isla got reflux/excema/ dairy allergy and other intollerences. Unfortuantley there is no easy answer to preventing allergies tho.

Yeah my friend was telling me today that they are now suggesting if you don't have allergies in your close family then you should not avoid nuts etc whilst pregnant as they think that may be contributing to the problem. Doesn't always work though, we have no allergies in either family I didn't restrict nuts, eggs, diary etc and yet he still got an allergy (although he does have the most common one, and I read that 10-15% chance even if parents have no allergies of getting diary one.)

I would just try to do as the others have said and hold off introducing the things you have problems with. Also follow 4 day rule when introducing solids, we strictly do this with Spencer and found that parsnip gave him a flare up of his ezcema which if not following the rule I never would have thought of as a cause.

Yeah basically when you introduce a new food you give a little bit and then build that up each day and don't introduce anything else new in those 4 days (but is fine to give foods they are ok with in those days), if the new food causes a reaction you should see it in those 4 days.

With the breastfeeding you may notice foods you eat affect the baby, i.e some might give baby wind etc. I ate a lot of onions one day in a curry and it gave Spencer terrible wind. But with allergies he might get ezcema or be a bit rashy, normally plunket would then suggest that you trial cutting diary (or other foods) from your diet for 2 weeks to see if it helps. My friends baby got terrible nappy rash when she ate too many tomatoes so she is gonna hold off introducing those, although she thinks it might have just been the acid in them rather than an allergy.
Sorry for the waffle, hope some makes sense.

If problems do arise (here's hoping they don't, of course!), you could try keeping a food diary of your intake, along with any symptoms that appear in baby - patterns sometimes appear, and that can be helpful in knowing if something needs to be cut out.  I was completely dairy-free while breastfeeding Ella for 5 months of it, and it made a small difference for her (her eczema went right down), but wasn't the answer in the end, and the same formula the gremlins were on was what she needed instead.  Quite a few of us have gone dairy-free while feeding our wee ones so there's support for you here if you need to do it, but I'd still say don't go there unless you see a problem to start with - fingers crossed you mightn't have to cross that one.
