I've got:
Me
dd
dh
my bump (feel he ought to be included)
mum
dad
SIL (recently divorced so no accompanying BIL)
MIL
FIL
Luckily dh is doing the Christmas dinner. I actually don't mind too much about being beseiged by relatives, since dd will be centre of attention all day (and won't need the usual intensive one to one input from me to stop her from getting bored)
