Query: Fine if you don't mind the crying

Dr Ferber understands sleep. But I don't think he really understands babies. His "program" is scientific, but doesn't take a baby's feelings into consideration. The exact scheduling of so many minutes of crying or so many ounces of milk assumes that all babies are alike, and they aren't. My baby cried so hard he threw up, and the book says to clean him up "matter-of-factly and then leave again", and not to "reward him for throwing up" (exact words!) I'm sorry, but my baby was terribly upset and needed some reassurance. Yes, I bet the "program" works, but at what cost to my child's self esteem and to my relationship with my child? I found more compassionate answers in a book called The No-Cry Sleep Solution written by a mother of four who dealt with sleep issues with her own baby and clearly understands that human beings require more than a quick-fix solution.
