A.D.
My DD continued to wake up for "midnight snacks" at the "milk bar" until almost exactly 1 yr. We did a very cold turkey method - I just stopped nursing her (with the exception of like two times) - and since we BOTH were ready...it worked fabulously! She was done - I think the night stuff was purely for comfort (for her anyway) and once we finished that, she also started sleeping in her own bed - all night - FINALLY!!! WOOOHOOOO!
So, I guess my advice would be to just wait it out a little longer if you're willing to do so. It may just solve itself in a few more months! Other than that...I have no idea! This is so totally a "learn as you go" thing, isn't it! LOL! :)
