Speaking as a labor and delivery nurse, I can assure you that there are permanent changes to a woman's uterus. Any doctor or nurse practitioner can tell if a woman has had a baby.
As for feeding that baby, that struck me also. How many hours was he away from Claire? Anyone figure that out?
Maybe they gave him something on the Searcher.
He did not have diapers. Nothing to change. Maybe they did it like the primitive tribes that sense when the baby is going to let loose and hold them at arms length. This big plot error bugged me a bunch.
-- Claire who is a nurse, a mom, and a grandma
Not only that...but I found myself wondering how Jack was going to explain his missing appendix..what Kate's GYN is going to think when she goes for a checkup - doesn't a woman's body change after giving birth (or is it only temporary?)
These things are going to keep me up at night! ;-)
