Continuity mistake: Susan comes home carrying bags of groceries. When she first sees Chloe sitting at the door, a box of Kix cereal is on the side of the bag next to her body, but as she says "Chloe", the box is on the other side of the bag, away from her.
Other mistake: When the patient Isadore is brought in, early in the show, he is transferred from the stretcher onto a table, and we can see him deliberately move his right hand out of the way of the other actors moving him. He is supposed to be unconscious and very seriously injured so would not have done this is real life.
Continuity mistake: Susan and nurse Connie are talking to the fraudulent doctor - Susan has her clipboard at waist level and is lifting one page up with her right hand. The next shot shows her holding the clipboard down at hip level and both hands are on it. There was not enough time for the change.
Continuity mistake: Carter, referring to the patient Isadore, announces that he can't find a pulse in his leg - as he says this, his stethoscope is around his neck. Doug orders him to find a surgeon and suddenly the stethoscope is in Carter's ears, but there was no time for the switch.
Continuity mistake: Doug introduces his girlfriend's son Jake to old girlfriend Linda who is holding her coat over her arm with her hands clasped together. As she says hello to Jake she puts her hand up to her hair, but from his angle we still see her hands together. This continues for the next couple of shots as they chat.
Motherhood - S1-E25
Continuity mistake: Near the start of the show, Susan rushes into the ER with Chloe who is in labour. Carter is sitting behind the desk and he tips back, falls over, and takes his coffee down with him. Then he is suddenly standing there with a wheelchair for Chloe and he also hands Susan a mug of coffee from the counter, which somehow just appeared there. All this took place in 6 seconds, which couldn't have happened in real time.
Motherhood - S1-E25
Revealing mistake: When Susan and Chloe's mom comes to the hospital to visit, Chloe gives the baby to Susan to hold. If you look closely you can tell the baby isn't real but is actually a doll.
