Revealing: All the babies in the incubation room are, very evidently, dolls. When one is driven inside, his cries are heard but he doesn't mouth them.

Revealing: The baby that opens the episode is a real one in the close shots and a doll in the others. First of all he doesn't move, and second, his skin colour is totally different.

Continuity: The first baby dies on December 2nd. House's clinic patient is four months pregnant, and is given an expected due date in late March. Her due date would actually be in early May, if she's in her fourth month in early December.

Revealing: Exactly ten minutes to the end, the couple with the baby Maxine are waiting to hear how she is doing. The mom and the husband are sitting on a bench outside the room in which their daughter is being treated. The mom lies down on her husband. She is supposed to have given birth only recently, so she still has a big tummy. As she lies against her husband, however, it is clear that she is wearing a prosthetic stomach: her blue T-shirt tucks and crinkles into and around it in a way that shows it is not an organic part of her.
