We are having a child free wedding, including only the kids who are in the wedding, and we told my daughter she could invite one friend so she felt like she had someone to hang out with all day.
She was having a tough time deciding who to invite, so FH decided she should be able to invite whoever she wants in order to feel comfortable and have fun, because it's her day too, in a way. (We don't expect her to invite more than 4 or 5 people). She does have a few friends whose parents are invited, but a few more whose parents we know, but not well. Would it be ok to invite their kids but not them, as my daughter's guests? (We're talking teenagers here, not 6 year olds).
