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.
“I always say bedtime and nap routines can start from day 1. A child is never too young to learn healthy sleep habits and routines! But to get a baby sleeping through the night there are a few things I check. The baby should be at least 15 lbs, no medical concerns, and on a healthy growth curve approved by their pediatrician. If all these points are met, then I'm ready to start getting that little one sleeping through the night!"
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.
