There will be SO many years ahead where our kids will want to invite friends etc and have huge parties. Why don't you make a special cake, invite only close family and friends to join you if they WANT to at the zoo or somewhere else special that you will go and just enjoy a day our instead of organising a party. That way if nobody goes, doens't matter because you will all have a ball and a fun day out and if a few people decide to join you ~ the more the merrier!! (Mmmmmmm off to contemplate something similar for DD's 4th party coming up....)
