If the baby’s legs go through her legs shouldn’t the baby’s arms go through the arms? With all that practice following along with mom babies should be able to walk immediately after birth like the rest of the natural world.
Most babies turn head down in the last few weeks before birth- a typical pregnancy lasts 40 weeks. At 30 weeks like in the picture of the baby would probably still be in a head up position.
When I was a kid, my mom was usually pretty laid back. But, if we were being smart asses, I’m pretty sure she could have reached us from halfway across the room.
