They have separate placentas and sacs, with one being at the front and left of the uterus and the other back and right. Techs can't get a photo of them together! Used to be one would be active and the other was sleeping, but as Lefty has caught up in size, they're closer to the same schedule. I hope that makes it easier for feeding time when they're here. :)
11 days until we know their genders. SO excited!
