With Masyn I was super cautious, she was MPI but outgrew by 12 months, and had no other allergies/reactions...I still didn't feed her eggs til 1, seafood & nuts til 3. She is fine with every kind of food now.
With Spencer (MPI too) I threw caution to the wind and fed her egg yolk at 7 months, had a reaction (hives and very cranky, not sleeping, diarrhea) then again at 13 months with the whole egg and same reaction. I did do seafood at 3 and it was fine, but I still don't have the guts to try nuts of any kind.
We have a huge family history of allergies/asthma so it freaks me out!
