We want to invited some kids, ages about 11+ to the reception because they are old enough to behave, also my brother is 11 and FIs cousin is 10, but FI's niece is/will be 2 for the wedding and I'm nervous about FILs reaction. MOH will also have a baby at time of reception, but she knows we don't want babies there, and others have young kids too. Is this ok to do? Setting a certain age limit? Thanks for any input.
