A consistent bedtime routine is the cornerstone of good sleep for children. It should also be a time for parents and babies to bond. Bedtime routines need not be complex. Bathe your child (if you like), change her into pajamas, read her a story, sing a song and feed or soothe her, then put her in her crib. The key is consistency — performing the same activities, in the same sequence, at the same time each evening.
Though many of the parents I see in clinic have put up with terrible sleep for years, sleep training is a safe and effective tool to help babies learn to soothe themselves at night. For this guide, I reviewed the literature on infant sleep. As director of the Pediatric Sleep Center at Yale University, I have extensive experience helping families to address sleep problems. I have also written a book on the topic, which was inspired by sleepless nights with my own children.
"My well-meaning friends are all Ferber addicts. I went against my own instincts with our son and tried with no success. They promised it would get better each night, but on the third night he cried for three hours, much longer than the first two. I felt like a failure and, of course, stressed from all of his crying. Babies have their own personalities, and you shouldn't feel pressured into doing something that 'works for everyone else.'"

Exhausted parents may be eager to get training underway—so how do you know when to start sleep training? “Most infants are ready for some sort of sleep training at 4 to 6 months,” says Lauren Kupersmith, MD, a clinical instructor at the department of pediatrics at NYU Langone Medical Center. “While some pediatricians adhere to the guidelines that infants are ready to be sleep trained when they achieve a particular weight, I feel it’s much more appropriate to wait until they are developmentally ready to self-soothe, at about 4 months old.”

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.
