We did the big grocery shop yesterday and got three different types of peanuts and peanut butter! The peanuts are not for the kids (may contain traces of milk) but we sucessfully tried #2 on a bit of peanut butter this morning. The immunologist had told us to do it on a weekday morning in case we needed to get medical attention (although she assured us that it was very unlikely given his clear test results). We watched him closely and no reaction. Yippee!
We've been singing the "Peanut Butter Jelly song" all morning.
