There's never a perfect time to start sleep training. But if you're using the Sleep Lady Shuffle method, it's best to start when you know you'll have at least three weeks without any changes in time zone, cribs, or bedrooms—especially if your baby is alert and sensitive. The most popular night to begin is Friday because of the upcoming weekend. Some parents use vacation days so they won't have to worry about being at work in the morning. And remember that you'll always be more successful if your baby has been napping well.
Cry It Out: This method involves putting your baby into the crib drowsy, but awake. The goal is for your child to learn to fall asleep without your help, so that when your baby inevitably wakes up in the middle of the night, he or she will be able to go back to sleep on his or her own. You say goodnight and leave the room—even if your baby cries. Then, you go back in at increasingly long intervals to briefly reassure your baby. It can be difficult to listen to your baby cry, but parents who have been successful with the technique report that it results in fewer tears overall and more sleep for everyone.
"My first cried it out, and all was well. My second cried it out but it took much longer until all was well. My third, if allowed to cry too long, literally freaked out. He threw himself around his crib and would rarely calm down and fall asleep. On the rare occasion that he fell asleep, he'd wake up within minutes screaming bloody murder. Letting him cry it out was clearly not working so I looked for other options. Find your child's groove. You'll be glad you did."
That said, sleep training isn’t a must-do for everyone, and many families who skip sleep training go on to have a child who learns to sleep through the night on her own. “It’s your family and your child, and I think there’s a misconception that pediatricians will force sleep training on your family, when that’s not the case,” Gold says. Experts emphasize that the best approach to sleep training is the one that fits your family.
