How do you deal with other people offering your children animal products? What do you do when they go to school/sleepovers? 
I'm worried about these things when I have children. I plan on teaching them at a young age why we don't eat the things others do but I'm afraid if another adult offers it to them, they won't know if there are animal products in it. 
Do others normally respect your wishes and feed your child what you tell them to or have you had some people do it anyways?
