There is another post about a 10 month old not sleeping, you may want to read the responses there too...my 1st child didnt' sleep through the night until she was about a year old. We would put 10 binkies in her bed so she could find them herself! This finally worked, but it took a while. As for night feedings, I think my peditrician told me that by about 6 months they shouldn't NEED a nighttime feeding - that doesn't mean they dont' WANT it. So, once I realzied she didn't NEED that feeding, I quit nursing her back to sleep. I dont' think she was really hungry, just wanted that comfort and was used to it, like a bad habit. So, check with the peditrician, make sure it's ok to stop nighttime feedings, then just try to be patient. I am a fan of crying it out althought it's VERY hard for me. The way I did it was to give them some time to settle themselves, then I'd go in after 5 minutes, calm them down (without picking them up) and then leave again. this time I'd wait 10 min. before I'd go back in. No eye contact, just patting and laying them back down in bed. Then I'd go out and wait 15 minutes. It takes a while at first, but after a few nights of this routine, they get the picture and learn to deal with things on their own. Another thing that helped me TREMENDOUSLY with my 2nd child was a video monitor. That way when he fussed, I was able to actually look in his room and see if he was fussing with his eyes closed and laying down, or if he was standing up and eyes open, etc. To me, it made a difference b/c it always seemed like when I'd fianlly say "ok, he's been crying for a while now, I'm going to go see if I can calm him down..." then I'd check the video monitor and he was sitting, or laying down and you could tell he was about to go back to sleep on his own.
Good luck!
