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.
"A young child cannot yet understand what is best for him, and he may cry if he does not get what he wants," Ferber writes. "If he wanted to play with a sharp knife, you would not give it to him no matter how hard he cried, and you would not feel guilty or worry about psychological consequences. Poor sleep patterns are also harmful for your child and it is your job to correct them."
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.”
"My first daughter was sleeping through the night (10 p.m. to 9 a.m.) by 6 months. We had a complete bedtime routine: a bath, a book, a bottle, then to bed, a little music in the crib, and asleep in 10 minutes. It was wonderful, but that scenario didn't work for my second daughter and hasn't worked for my son, so I've tried different things for each of them. Sometimes a plan doesn't work. Listen to your baby – he or she will tell you what you need to know."
Sleep training is a loaded phrase, and one that is often used synonymously with letting your baby self-soothe, or “cry it out,” but that’s not the whole picture, says Alanna McGinn, a certified sleep consultant and the founder of Good Night Sleep Site. “It’s more about being able to teach your baby that they are capable of falling asleep independently,” she says. You want your baby to be able to nod off on their own—ideally without nursing, rocking or using a pacifier—because whatever tools they use to fall asleep at bedtime are the same things they’re going to wake up looking for during the night. Yes, this can feel unloving and even downright cruel. You’ll find experts on both sides of the issue: Breastfeeding advocates say it’s normal for babies of all ages to wake up multiple times to nurse, and even the sleep coaches interviewed for this article disagree with how much crying and distress are acceptable.
