Her head is where???

We went to the doctor Monday and needless to say babies are doing great!!! Every measurement is right where it should be. The babies are in the 70th percentile for their weight. Baby A is 4lb 2 oz and Baby B is 4lb. 3 oz. That is quite large for twins at this gestation. Most babies, according to our doctor, weigh about 5-6 lb at birth so we are well on our way.
Doc wants to do delivery on January 7th or 8th. It seems so far, but it's really not. I could go into labor at any point now. I feel really good. Still tired, but good. Baby A had moved slightly. He is now butt down in a kneeling position. I hope he is on his way to moving head down. I would love love to deliver naturally and doc will let us try it. Baby B is still laying sideways. To be exact, her 'girl parts' are on his head. There is the sac that keeps them apart, but we thought that was pretty funny. It's amazing to me how they are squished in there and the positions they get into!!! We go back on the 29th and then weekly after that.
I have officially started packing. Just throwing things in a bag as I think of them. My kids are setup with grandma if need be and my sister is coming from about2 hours away to take care of them too! I hope everything is set and ready to go when time comes!!
