We are breaking out of the alternating-between-parents cycle this year and we're delighted about it.
It should have been my family's turn, which would have meant us hosting everyone as we have biggest house. But we had DC2 a couple of months ago and fortunately my Dad realised (for once!) that we might find it difficult to host this time, so suggested we give it a miss this time.
So we are going to stay at home with the DCs in our pyjamas, open presents (which will be minimal), and eat a normal roast dinner. Our aim is to have a frugal-but-fun day - I've been saving our Tesco vouchers all year and they should cover the food, drink, and hopefully presents too. The emphasis will be on spending time with the DCs and each other, which we don't do that often as DH is working his nuts off.
We will then go to PILs for a day, probably Boxing Day, and will meet my lot for a pub lunch some time over the Christmas period.
It has the potential to be the best Christmas EVER, and the cheapest (last year we spent an effing fortune and weren't even hosting). Do it, OP!
