sorry - DS' not settling.
Treedelivery - what d'you want to know?
DS first showed signs of allergy/intolerance at about 4mths but it took until he was over a year to see a consultant, by which point he was on Neocate (which I found out about on here) and couldn't eat fruit/tomatoes/peppers/aubergines/potatoes/ red meat/dairy/wheat/soya/eggs and had become anaphylactic with sesame. I had to stop bf as the restricted diet was making me ill.
My paed consultant was useless (but in fairness I suppose they do have to be jack of all trades ) I basically walked in to see my GP and demanded he be referred. In London he's had IgE levels checked against certain allergens and skin prick tests (though I accept these can be unreliable and can give false negatives as well as positives depending on how the body is coping at the time)
DS is now 3 and we only avoid cow (milk/cheese/meat) pork / sesame / raw tomato & pepper / wheat / soya and egg (though now he's developed a dustmite allergy ) it's utter bliss in comparison to life before. Though we still can't eat out and parties are, well, avoided as much as possible at the mo but it is getting better
