WE have every allergy in the book. The doctor has told us that the longer you postpone the introduction of a new food the less likely a child is to develop an allergy.
I'm allergic to fish so I'm not letting the kids have fish until 7 (the magic number for allergies when new ones don't pop up in general).
The babysitter gave my son eggs and peanuts when he was 2. Wulla. He has those allergies now.
I am more than a little appalled by the responces on here. You have a child who is deathly allergic (That's what having an epi-pen means, We have 2 for each child) and people want you to just try it? And what, see if he swells up and can't breathe?
Don't introduce pb! Talk to your doctor before you do anything that could change the course of your child's entire life.
If I knew 7 years ago what I know now my children's lives would be easier and a lot less limited. It's easier to keep it away in childhood then to say "Sorry, you have to avoid this for the next 70+ years"
