I have two dbs. both have one kid. one has two teenage step-kids - they're 17 and 19 (lovely kids but I don't know them well) I'd really like to invite both dbs (as well as my mum, fil and step-mil) for christmas but just haven't got the space for everyone. so can I say to db - I'd love to invite you but we ain;t got the space for all 5 of you? - I assume this is less offensive than inviting them but saying there's only room for three (pretty awful imo) I just feel horrible only inviting one db. what do people think?
