got my 1st xmas dinner to make...

we're having christmas dinner at our house this year, as we now have a house with enough room for everyone!! Trouble is i've never had to cook for 6 (+ my 2 year old)before!!
slightly worried as my MIL was talking about home made gravy and stuff (i dont even like gravy so wouldn't be able to test it!)
I'm not the best at managing to time everything to be ready together at the best of times!! :/
