When my kids go to other people's houses the parents don't call to ask "is it okay if or child eats Cheetos and Sierra Mist?" because there is a general assumption that as long as a child doesn't have allergies you can feed them when they're at your house. And I respect that when my kids are at other peoples houses.
So, anyway, how do you all handle other people's kids and food in a society where traditional foods are often considered unsafe? Personally I think Cheetos are WAY more unsafe than some raw milk in a smoothie but I don't exactly want to get into this discussion with the parents of my kids' friends.
