When I was still in the throes of sleep deprivation when my son was a toddler and never slept , my grandmother made a comment that has stuck with me for years. She said that kids never had sleep problems when she was a young parent. I've always wondered about that. We all slept as kids, and our parents worried about a lot of things but not about getting us to sleep. Why are there thousands of books these days instructing parents how to teach their kids to sleep? Isn't it a biological imperative? Why wasn't my kid just sleeping and letting me sleep? Was it something in the water?
