J.S.
M.,
My experience with this is almost IDENTICAL to yours. My son never slept through the night, I gave him a bottle to get him to sleep and I gave him a bottle once during the night. Around 13 months, I couldn't take it anymore and we decided to read all the books you did. We finally decided to let him cry when we put him down and then go in every 15 or 20 minutes to pat him on the back. The first night was horrible, he probably cried/screamed for over an hour. The second night was bad too, but the time he cried decreased until the third or fourth night he just laid down and went to sleep. I cried the first couple nights as he cried because I felt so horrible, BUT I also cried the first night that he fell asleep on his own without crying!!! It worked for us and although he occassionally will cry for a minute or two when we first put him down, that is it. Occassionally he wakes up during the night, but we just go in to check to make sure there isn't a poopy diaper or some other issue and then we just pat him on the back and walk out. The key is not to pick him up unless you have to take him out his crib to change him.
Hang in there and know that it will get better!! You will be so glad you did this!
