Hey Sleepy Baby understand and sympathize completely with families who choose sleep training. Hey Sleepy Baby have been there. In any of their guides or programs, you won't find any traditional sleep training techniques or CIO. They simply cannot recommend methods of crying or separation-based sleep training given what they now know about infant brain development, neuroscience, sleep biology, feeding, and attachment. Naturally, babies cry; as a mother of three, they understand that. Even though your baby might cry when you make a parent-led change like night weaning, you'll learn how to help them through it instead of leaving them to figure it out on their own. They will teach you when and how their child needs to cry in order for you to be able to support them without worrying about "spoiling" them or leaving them alone with their emotions.
