My son also went through a horrible sleeping change between 6-9 months. It just gradually changed, and we changed with it. Then by 9 months, we realized it was out of control. All of the sudden, he was waking every 2 hours to nurse...after being assured by the drs office that he didn't need the nighttime feeding at this age, I read the literature they sent me. It was about using a modified cry-it-out program. I know many moms have different philosophies on CIO, so I don't want to start a debate...I just know that we used what was recommended by our pediatrician & it worked! Within three days/nights, we were back on track! My advice is to contact your pediatrician & see what he/she recommends. I also used some of the advice from the book, BabyWise. Look at the options & choose what you think might work with your family. HTH, Best of luck!
