I've reached the part of planning where I'm finally getting to trim down my guest list, and I'm trying to get my portion of the invitations down to 50. One person I've known I want to invite from the moment a wedding crossed my mind was my old piano teacher who was a very close friend of mine and I love very dearly. However, I only met her husband once and haven't met her kids because we are a couple hours apart and don't get to see each other really. My question is, could I just invite her and let her husband take her young daughters (4 and 2 if I remember correctly) for a daddy-daughter day? My wedding will be laid back and in the late morning or early afternoon, and won't be terribly long at 3 hours max, so would this be okay? I don't mind having kids at the wedding at all, and wouldn't mind meeting her family, but I'm trying to be conscious of my number of people. I don't really mind either way, but just wondered if that's totally rude or a nice break for her.
