Allergies are the worst! In October we found out that Sean is allergic (4+) to eggs. It hasn't been too hard to deal with because I can give him a lot of fresh fruits and veggies and he likes most meat. There are times that I do get nervous, however. The other day I left him with a babysitter and when I went to pick him up the other kids were eating sugar cookies. The babysitter knows that he as an egg allergy, but was about to give him the cookie. His reaction to a cookie wouldn't have been too bad, probably just a tummy ache and a rash, but I still over-reacted just a tiny bit. (I don't want to ever use the epi-pens that I carry around.)
Sean has been pretty sick over the last month and I finally got an Amoxicillin prescription for him. About 9 days into the prescription he got a rash all over his entire body...turns out he's allergic.
I hope he doesn't get seasonal allergies too!
