content: Supposedly Dr. Denmark helped develop the pertussis vaccine in the 1930s. That's noble. However, I think the ideas contained in this DVD are dangerous. This video suggests feeding your baby every four hours and how its normal for a baby to cry from 2pm to 10pm every day. The suggestions in this video -- leave your baby to sleep on their stomach and no variance in feeding times for breastfeeding (babies digest breastmilk faster than formula, and may need to be fed more often) -- contradict the latest scientific research. If you follow the method outlined in this video, your baby will cry from hunger and neglect. And your baby will sleep -- from lack of calories and sheer exhaustion from trying to tell you that they're starving. I feel sorry for the women depicted in this video who seem well-intentioned and are looking for guidance. If new parents are looking for a baby routine to follow, this is not it.
