Food allergies??

As

I just started giving purées to my 5.5 month old (6 mo on the 29th) Day 1: Peas. Day 2: Peas Day 3: Peas and Sweet Potatoes. On the 3rd day she started wheezing in the afternoon. I completely stopped for a few days because it freaked me out. Should I try a different veggie or wait and talk to our ped at the 6 mo checkup???
