The benefits of sleep training baby can be substantial: Everyone in the household will be well rested, and sleep is essential to baby’s development. A landmark 2007 study from the National Institutes of Health suggested that critical brain-development periods are dependent on adequate sleep. “Sleep training baby may not be fun, but I always tell families that it’s not dangerous, and developing good sleep hygiene is, in my opinion, one of the best things you can do for your child,” Gold says.

Crying isn't the goal of this sleep training method, but advocates say it's often an inevitable side effect as your baby adjusts to sleeping on his own. They say the short-term pain of a few tears is far outweighed by the long-term advantages: A child who goes to sleep easily and happily on his own, and parents who can count on a good night's rest.

"I have two kids. The first one was never left to cry it out – we rocked, sung, walked, drove her to sleep until she was old enough to be read a story. Then, with baby number two, I decided to try CIO and after one night, it worked. At 12 months, she goes to sleep at night by herself and never cries. It was the best thing I did. My husband was against it, but he wasn't the one up four or five times every night for nine months straight! Now our household is very happy and everybody sleeps well."
There’s also no need to institute a regimented cry-it-out plan if what you’re currently doing is working for your family. But good sleep habits never hurt, and being able to fall asleep on one’s own is a necessary life skill. If you sleep-train at a time that’s developmentally appropriate for your baby and with the basic ingredients of healthy sleep in place, you can minimize the amount of crying your baby (and, let’s face it, you) will do.
