My sons ezcema routine when he was younger was creams applied 5-6 times a day, if slighty worse up to 8, big flare up sometimes up to 15.
It took over my whole life.
it was very depressing.
anyway, food.
only give one new food at a time, no mixed fruit , or veg.
avoidance of cows milk is because milk allergy is common in infants, ( and is the good one for outgrowing BTW, not all, but im most cases)
and in the intolerance area, wheat does cause problems ( as well as cows milk)
Dont try egg for a long time, and if you do leave it for the 2nd year, and try very well cooked first.
If its classic food allergy , you will see the signs very very quickly.
If its food intolerance, maybe in a nappy later, and then the skin flaring up and a few nights spent crying.
Often food intolerant infants sleeep badly from gut pain as they are place flat in cot. ( lift feet slightly)
What sort of food are you giving?
i cant remember if you said breast or bottle or both?
What atopic diseases or food allergy are in your family, ( if any?)
Race does have a factor in food allergy, asian and middle east children in this country are REALLY developing severe milk (beef) allergies.
As a totally unimportant note, but interesting, common foods in other countries are causing a rise in food allergy, so japan have problems with rice and fish, and france have problems with celery and mustard.
Do you know what the difference is between intolerance and classic food allergy?
A really good book ( which I dip into all the time) is 'the complete guide to food intolerance and allergy' by prof jonathan brostoff, published by Hamlin.
hope this helps, sorry to waffle on.
