I've been trying to train my 15mo old to fall asleep on his own but he gets so upset he throws up every time i leave the room. any suggestions?

So sorry: This is such an emotionally painful process i feel for you! we had great success with this book (for our first baby)... Ok success with it for the second. A lot depends on the personality/temperament of the kidlet. But a lot does have to do with the parents too. In the end we try our best and the kids get bigger despite it all.
