In our house we tend to have Christmas films on all morning and last minute wrapping/preparations going on.
I always make Nigella's Christmas rocky road and put into little gift bags as sort of a little Christmas Eve gift for everyone.
Then we set off it my mums with all the prezzies, duvets etc.
We used to have a Chinese takeaway as our traditional Christmas Eve dinner while we watched a family film but the past few years we've gone for an extended family meal at the loveliest country pub. They make it look so gorgeous and we usually get the big table next to the open fire.
Then we get back to mums, get into Christmas PJs, make some cocktails and even though I'm almost 28, mum will make us all feel our presents and try to guess what she's got us and never confirm or deny 
What are your family traditions for Christmas Eve?
