Dr. Quinn, Medicine Woman - S1-E1

Dr. Quinn, Medicine Woman - S1-E1
Factual error: When the woman is giving birth and Dr. Quinn has to perform a c-section, she gives the baby to Mrs. Cooper, and after about a minute, she gives the baby to the mother. Dr. Quinn then leans towards Mrs. Cooper and they smile happily; she doesn't attempt to continue the "surgery". Even nowadays doctors need several minutes to close up again after a c-section, so there is no way that Dr. Quinn was anywhere near finished. Leaving the patient cut open on the bed is pretty irresponsible, something she would never do as she has to prove that she is a good M.D. (00:30:00)

(01:05:30)
Dr. Quinn, Medicine Woman - S1-E1

Continuity mistake: Before Loren's operation, when Dr. Mike shows Jake how to administer the chloroform, she holds the bottle in her left hand and the rag in her right hand, but in the next shot both items have switched to the opposite hands. (00:21:20)
Continuity mistake: When Michaela and Sully appologize to each other at the end of the episode, in the first shot, all of Sully's hair is behind the blue headband. In the next shot, his fringes are not underneath the band anymore. (00:45:30)

Visible crew/equipment: When Dr. Mike tells Jake that he's not ready to go home, a black chalk T-mark is visible on the floor near the door. Then as Jake pounds on the door he tells her he has a business to run, and the moving boom pole casts a shadow on the wall, at the top, right side of the screen. (00:26:35)
Visible crew/equipment: Shadow from the boom is visible above Sully when he's talking with Michaela about Jake's condition. (00:27:26)
Continuity mistake: Matthew invited Ingrid to eat with them in the previous episode. In this episode, he acts like he's meeting her for the first time.
