We are being descended upon! We have DD2, SiL and DG2 coming on the Sunday and leaving on 27th. Then 3 of the remaining 4 children, DS1, DD1 her husband and two children, DD3 her husband, baby and puppy, will come for lunch on the big day. DS2, partner and sons will go to her family but call in for present opening, champagne and nibbles on the way. That amounts to 12 people and a baby so we are having 2 tables - one for the grown ups and one for the children, which DH says he will erect in the garage! 
On Boxing Day (my favourite day!) we'll eat after DH and DS1 come home from the football and anyone is welcome.
The next day - we sit down. 


Then it's New Year when we have DH's brother and his wife to stay. Which is great, as she is the nearest thing I have to a sister.
