bringing up baby

have you guys watched the series on youtube titled Bringing Up Babies? its about 3 different ways of taking care of a newborn. i couldn't finish it though. one method there is to leave the baby to sleep on their own from 7pm to 7am. then they have to be left outside for 4 hours everyday on their own. and the parents are only allowed to cuddle their baby 10 minutes per day. its so heartbreaking for me that some babies are raised that way. i mean yeah the end result is great but i would never put my baby through that. i'd rather have sleepless nights cuddling my baby.
