I always keep all the kids at the table until everyone is done and cleaned up and then we all go to the playroom together (this is partly because they are all little and cannot play unsupervised). I won't force anyone to eat either, but try to serve meals that have a couple of components so that everyone eats something (ex. soup and cornbread and tomatoes). I don't think it's fair of parents to ask you to not serve something that they are serving (and sending with) the child! Also, I have a policy of no food being brought from home; that is because I don't want kids coming with treats and then everyone else will want some too. I serve the same thing to everyone, no substitutions. I also don't serve dessert, just once every couple of weeks I will make cookies or something as a treat.
