Prepare yourself for a few difficult nights. Hearing your baby cry can be excruciating, as every parent knows. During the waiting periods, set a timer and go to a different part of the house, or turn on some music, so you don't have to hear every whimper. As one BabyCenter parent says, "The first week could be rough. Try to relax and know that when it's all over, everyone in your household is going to sleep more easily and happily."
Also on the far end of the cry it out spectrum is the Baby Wise approach by pediatrician Robert Bucknam and co-author Gary Ezzo. In their book On Becoming Baby Wise, they advise against feeding babies on demand around the clock and instead advocate a parent-led feeding, wake, and sleep schedule. Their method involves following a strict nap and sleep schedule and putting your baby down awake so she can learn to soothe herself to sleep. This means there will be some crying, especially at first, as your baby adjusts to your schedule.
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.
Fifteen minutes is all you need to perform a soothing bedtime ritual that will help your baby's mind and body prepare for sleep. Remain in his nursery or near his crib and choose the same two or three quiet, calm activities, such as reading or singing. Be sure to keep anything stimulating (tickling, TV) out of the equation. For babies over 6 months, incorporate a favorite stuffed animal or blanket into the routine.
McKenna advises against sleep training and encouraging babies to sleep for long stretches at night. Instead, he urges parents to follow their babies' cues and allow them to wake frequently through the night to feed. A strong advocate for co-sleeping, McKenna encourages bed-sharing and other co-sleeping arrangements, such as putting the baby in a bassinet or crib at the parent's bedside, while also following standard SIDS safety precautions – for example, making sure there are no blankets or stuffed animals around him.
If your baby is older than six months, don’t worry, McGinn says: “It’s never too late to develop good sleep habits.” Dickinson says he finds nine months to be a bit of a sweet spot for parents in terms of getting babies to sleep through the night. “They are at a good age for understanding routines and don’t need to eat during the night,” he explains.
