I just finished reading it and did it ever explain alot of things for me. Some of the references to medications are pretty out of date but on the whole very helpful, with something of value for everyone. It feels so much better to know that you can find something that will work and that it will get better. For us it was the Jolly Jumper. I think he was getting sick of being held or imprisoned (chair or swing) all the time. He is 13wks and some independance has done him a world of good. He is the happiest I have ever seen him!
