When I was pregnant, we figured our babies would sleep in a crib. Beyond that, we didn’t have a plan for sleep training, other than that they’d sleep eventually. As we read more about attachment parenting, we realized we wanted to do a modified form of co-sleeping, with baby sleeping in a crib sidecarred to our bed. But one thing we never considered was Cry It Out (CIO), or the process of letting your baby cry themselves to sleep or “self soothe.” It never occurred to us. It seemed mean, and all the research I’d read said that it disrupted attachment and hurt breastfeeding. And honestly, I’m glad we never used it.
