A version of this technique called graduated extinction was popularized by Dr. Richard Ferber in his book “Solve Your Child’s Sleep Problems.” Here, parents check on their child at set intervals. Checks should be brief and to the point: Picking up your child, spending too much time hovering over the crib or otherwise offering more contact than a quick soothing word can be counterproductive. Some babies find these brief checks soothing and will go to sleep more quickly. Others will redouble their crying as soon as their parents leave the room. Parents need to make a judgement about whether or not checking in is helping their baby through this process. If you decide to use checks, I would recommend checking no more than every five minutes and resisting the temptation to check if your child seems to be calming down.
I have a 5 month old girl who has been inconsolable when it’s has come to going to sleep, whether it be nap time or bedtime. Up until 6 weeks ago she was very good at self soothing, where I’d put her down drowsy/almost asleep, put on some soothing music and she’d toss and turn for a few minutes and fall asleep. Initially I thought it was the famous 4 month sleep regression but now it’s starting to get out of hand. Just to note, she used to sleep about 30-45 minutes and occasionally longer. She seemed happy and content when she woke so I assumed she had had enough rest, although I would’ve preferred longer naps. Also to note, She currently sleeps anything up to 8 hours at night and wakes for a feed around 3-5am.
But when he was about three-and-a-half months old, the routine fell apart. “I would feed him, but he wouldn’t be asleep at the end of the feed,” recalls Welk. “I would rock him until he fell asleep and put him down, and then he would wake up 30 minutes later and I would do it all over again.” Desperate for some rest, Welk brought Greyson into bed with her, but then she ended up just lying still, holding a pacifier in his mouth all night long. “I didn’t know anything about sleep,” says Welk. “I didn’t know you couldn’t just rock them to sleep and then put them down.”
