Thanks everyone. Is such a tough situation because is hate to see her do some of those things to her newborn
I was going over the ezzo info website and posted it on facebook, sil is not on facebook, but her best friend is, and I'm putty sure that age suggested the book to sil, she jumped in first and said the book is great and its worked really well for all her family, but I had some very special people back me up and let her know the dangers of it without undermining her parenting.
I still however have a friend down the road that use the book religiously, it us scary, and I've got to start sticking up for myself when she tells me its wrong some if the things I do because it's'not in the book'
