It used to be something they did but I don't think they actually do it anymore
Its not in a mean way. They just "love tap" haha(: they just wanna make sure everything is okay!
If its taking g to long I've heard of doctors tapping the bum or the foot.
Depends on the situations. If baby doesn't cry at first they some places will spank baby but if baby Cry's they usually don't.
i dont think thats true, my first born didn't cry, and they didnt do anything they just did his weight and passed him back to me.
