Congrats on your Christmas baby!!
Honey, I feel your pain, I was like that for days and obviously then in a foul mood and utterly exhausted when labour did start properly. I would spend as much time on your hands and knees rocking your pelvis as possible, and walk up and down the stairs sideways in case it is babys position. I did all the tricks from spinningbabies and it didnt make a blind bit of difference but it gives you something to do that feels helpful, and it should work for the majority, clearly my baby was just stubborn! Also sleep as much as you can, keep hydrated and well fed and make sure everything you need for labour is packed and plans in place in case things go quickly once you establish.
