Continuity mistake: Molly's mother walks away from her daughter's bed and towards her ex-husband and has moved about a foot from the bed; the next shot goes back to Molly's face and we can see her mother's hand still on her shoulder, even though this would be physically impossible.
Continuity mistake: Near the beginning of the show, Susan is talking to Kerry while holding baby Susie and a stuffed Sylvester the cat; the toy is in a different position in each shot and in the last shot it has disappeared altogether. As Susan walks away, the toy is in the diaper bag, although we never saw her put it there.
Continuity mistake: When Carter first starts to confront the drunk patients Angel and Nathan, the door to their room is open behind him. Angel falls to the floor and the shot shows the door is now closed. The shot goes back to Angel laughing and the door is ajar again. Then it's closed again, and then open when Susan comes into the room. All this happens within a few seconds.
Continuity mistake: Near the end of the show, Susan is holding baby Susie and talking to Chloe through the chain-link fence. In one shot we see the back of Susan and Susie's head, but as the shot switches to Susan's face, we see the back of the baby's head again, without her ever turning her head.
Continuity mistake: When Doug is outside with his father, and the shot is on Ray, we can see a lot of snow in the air, but when the camera goes to Doug, there is no snow at all. The snow distribution on his father's coat change from shot to shot as well, too much to happen in only a split second.
Continuity mistake: Early in the show, Mark is going into an office to meet with Morgenstern and another doctor. As he opens the door in the hall, his bag is slung over his right shoulder, but when the shot changes and he's entering the office, it's over his left shoulder. He had no time to change it.
