G.M.
Sometimes I think you may have to try different things because I really think that different personalities respond differently. This is what worked for me: I continued night nursing and co-sleeping with my son until he was almost 2. I really felt it was time to stop interrupting our sleep and move to the next step. I firmly said to my son that "mommy's milky and nipples are sleeping now. In the morning we can nurse in the big chair." I made the bed off limits to nursing and repeatedly said "no, milky is sleeping until the sun wakes up" when prompted. It took only two nights. I hope it works this easily for you. But don't forget, if it doesn't, this phase (gift) will only last shorter time then it seemed when you look back at it... like everything else. Good Luck Mommy!
