Some of these experts think cry it out methods are not good for babies. Pediatrician and "attachment parenting" advocate William Sears devotes an entire chapter of The Baby Sleep Book to a critique of cry it out approaches. Sears, along with no tears advocates such as Elizabeth Pantley (author of The No-Cry Sleep Solution), believes that cry it out techniques can give your child negative associations with bedtime and sleep that could last a lifetime.
As we previously mentioned, introducing healthy sleep habits and routines as early as possible will help significantly during sleep training. If you haven’t already, try to establish a bedtime routine before you start sleep training baby — this will encourage healthy baby sleep patterns. This should be a series of soothing activities that help to calm your baby and prepare them for sleep - things like swaddling, bathing, and rocking usually work well, but every family’s routine will look different.
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.
Most sleep coaches say the ideal time to start sleep training (or promote independent sleep, not necessarily using the cry-it-out method) is based on your baby’s development, but is usually somewhere between four and six months, when your baby hasn’t had much time to get used to nursing or rocking to sleep. At this stage, most babies are also developmentally ready to learn the skill of falling asleep on their own, explains Jennifer Garden, an occupational therapist who runs Sleepdreams in Vancouver. Around four months of age, some babies go through a sleep regression because their sleep cycles change and there are longer periods of lighter sleep per cycle. “It’s a great time to work on independent sleep skills,” says McGinn. Other babies’ slumber derails around this time because they are working on new skills, like moving around and rolling. Some parents choose to wait until things settle down before embarking on a sleep-training method, but you don’t have to, says McGinn.
