im having the same issues hun....

our bub will be here by the 15th so will only be 10 days old by xmas and well thats scary enough let alone all the christmas shananigans!!

usually we do breakfast at MIL's and then lunch at one family and then dinner at the other family.

this year we have told MIL we wont be at breakfast and she was fine with that, mind u she had no choice it wasnt happening!!

she asked the other day if we thought we would make it to lunch and we said yes we intent on being there BUT will be playing things by ear.
hopefully it will be a quick lunch and we can get back home again if things arnt going to plan. there will be about 8 for lunch, thankfully the IL's are a small family, but i still wont have baby handed round person to person i dont want her feral for the night time.

then for dinner we are spending it with my family which works AWSOMELY becasue by then everyone is over it so its usually a quick affair!
mum has suggested that everyone will do the usual catering they do and then bring it to us so we dont have to go out nor do we have to put in any effort.
there will be about 13 of us for dinner, and again baby wont be handed round like pass the parcel, im hoping to have her in her room asleep, wishful thinking i know.

either way we will be making it well know she is a brand new baby and that we wont accept her being passed around unless they want to deal with her when she becomes a wild child because she is overwhelmed by everything
