Query: Please do not do this to any baby

If I could give this book negative stars I would.Anyone who at any time considers it normal or acceptable for an infant to cry alone and terrified in a crib until they throw up should not be trusted to give out parenting advice. There are much better, gentler books our there that will help you soothe your children to sleep.Please do not let your babies cry out for you in the night until they give up because they realize you do not care enough to help them.
