New photos and video added below (Charlotte is on the left in all photos and the two videos are at the very bottom of this post).
Charlotte and Claire are both doing well and continuing to eat well and regulating their own temperatures (with the aid of plenty of blankets).
They will probably come home together on Tuesday. They will have the "car seat test" performed tomorrow which involves them sitting in a car seat for 45 minutes whilst their vital signs are measured. This ensures that they can safely sit in car seats which are not designed for premature babies.
We had the opportunity to bathe and feed them today.
