ps. I just wanted to add that my daughter Marisa, who is not a sleeping baby has an anxiety / social phobia called Selective Mutism. It is a common trait for them to be restless, clingy and not sleep well from a very young age. Sleep school made her vomit, miserable and yell at the top of her lungs for two weeks. I am so glad I made the decision to surrender to her needs at that point because it wasn't her, it wasn't healthy and was probably all from her medical condition which I never knew she had until she was older. I would be feeling terribly guilty right now if I would have pushed her even more than her little body was telling me she was capable of.
