I gave out the invitations to DD's party just over a week ago. They are in reception and I'm still getting used to all the names. I forgot to put one girl on the invitation list and now that I have realised I feel terrible about it. They give out invitations in bookbags, but they all talk about their parties, so she probably knows she hasn't had an invitation. I don't have any limit on numbers because it is in a church hall. AIBU to offer a late invitation? Would you be offended as a parent? I'm worried they will just think it is because I'm trying to make up numbers and they are second choice, but I just made a mistake!
