This is a tough one! I would of course not want to ostracize someone just for being allergic to stuff. But it would also be really stressful for me to host someone when I'm not that informed on food allergies.

I would probably just host the kid and ask the parent to bring any food for both kids. That way, I wouldn't have to stress about potentially killing someone's kid!!

Would you have a playdate at your house with someone with severe food allergies?
