CIO (Cry It Out) method

The CIO (Cry It Out) method is a sleep training technique where parents allow a baby to cry for designated periods before offering comfort, with the goal of helping the baby learn to fall asleep independently. It involves establishing a consistent bedtime routine and gradually increasing the time before responding to the baby's cries. This approach encourages self-soothing, ultimately promoting longer, more restful sleep for both the baby and parents. While widely used, it requires patience and consistency, and some parents choose alternative methods based on their comfort level and their baby’s needs.
