What does this method entail?
As with all methods, after your bedtime routine you will put baby down wide awake and walk out. You may choose to set intervals of when you will check on baby or to make it even gentler, you will do the checks whenever baby's crying has reached a certain level of intensity. During the checks, you can go to baby, pick them up until they are calm + 1-2 minutes to further relax them, and put them down still awake. You would repeat the Pick-up/Put Downs until your child is asleep.
Who is this method for?
This method works beautifully on babies under the age of 6 months. It is gentle enough that baby is not being left alone for extended periods of time and you are able to help calm them if they are particularly worked up, but still allows them to self-soothe without you present. While this method works great for young babies, it may be too stimulating and confusing for older babies/children.
How long does this method take?
As always, it depends on the baby, but for a young baby using this method, progress will be seen in about a week's time. For an older baby, it may take longer than that, up to 1.5-2 weeks.
Please note that I do not necessarily endorse this method of sleep coaching, this is just meant to be a helpful description of a popular sleep coaching method.
