Good night, sleep tight, don't let the bedbugs bite. If only those phrases were all it took to put baby down. Getting a newborn to sleep through the night is one of the most talked about issues in infant care. Parents become fiercely supportive of their chosen sleep training method and its guru. Marc Weissbluth, one of the nation's most popular pediatricians and author of Healthy Sleep Habits, Happy Child that advocates a modified "cry-it-out" philosophy, is using his blog to take on Dr. William Sears, author of The Attachment Parenting Book: A Commonsense Guide to Understanding and Nurturing Your Baby, which calls for soothing baby until it falls asleep.

On his blog, Dr. Weissbluth discredits several studies Dr. Sears uses to prove that "crying-it-out" actually harms a child. According to Dr. Weissbluth, the studies show that allowing a tot to "cry-it-out" does not affect self-esteem, relationships with parents or the bond between parent and child. What's your opinion on cry it out?
