Hi amandaandmike, who got tested for the skin prick test? Was it you? I wouldn't think docs would do SPT for a one month old?
If you suspect so many things I would try & see an allergy specialist to get proper confirmation, especially if you already have a restricted diet, you don't want to be removing things from your diet that you really don't need to just on suspicion. You need as much as you can get while BF. But if you are both having tummy issues then sounds like food rather than environmental but its hard to say....
It sounds quite tricky, poor wee bubba having such itchy skin

I've heard the laundry balls are quite good. Have you thought about dust mites as well if he is so itchy? Do you have dust mite covers on the cot?
What sort of creams are you using for his skin? Has the doctor given any emulsifying creams? You can use them as a soap sub as well. And wet wraps might help if he is waking so much & not sleeping, although at only 1 month waking every 2 hours is quite normal anyway.

Hope you find some answers soon
