In the shot after the umbilical cord is cut on Linda's baby, the baby now has a belly button, something that wouldn't happen until the cord dried up and fell off.
Linda still has the prosthetic pregnancy bump under her costume while being given CPR, after she has given birth.
After Anya delivers Linda's baby, Linda is unresponsive. Anya begins CPR while Linda is still on the bed. In reality, the chest compressions performed during CPR cannot properly be administered on the soft surface of a bed. Any doctor, like Anya, would be aware of this fact.
