Cry it out sleep training, also known as extinction sleep training, is a popular method parents use to help their babies learn how to sleep through the night. This method involves letting the baby cry for a designated amount of time without intervening, which can be difficult for some parents to handle. However, the benefits of cry it out sleep training can be substantial. Not only can it improve the baby's quality of sleep, but it can also help parents establish a predictable bedtime routine and reduce the amount of nighttime awakenings. Additionally, cry it out sleep training can help babies learn to self-soothe and become more independent sleepers. While not for everyone, cry it out sleep training can be a useful tool for parents looking to establish healthy sleep habits for their babies.
