Firstly Id just like to say good on you for still breastfeeding. I stopped at 20mths and now actually wish I was still going. I really miss the closeness and comfort I could provide as well as the nutrients. What I have forgotten (amazingly) is how uncomfortable and irritated I was getting and also the night time waking up just like you.
I had actually posted here for help too because I thought I would never stop, but it eventually happened. My little one hated cows milk but I tried everyday, in all different shaped cups, with straws, anything to grab her attention. In the end the only way she had cows milk was in the car while I was driving. So thats what I did until she got used to having it. Next I cut down her feeds which took about 2 months, down to the feed before sleep. It took me a while to get the courage to break up this special bond, but one night I sat her down and spoke to her about how she was a big girl now, and she doesnt need mummies milk anymore, and she can now hug bear and go to sleep. I was shocked when she nodded ok, and went to sleep by herself.
Thats how it has been now since then, and she sleeps all through the night. If you really want to stop just keep slowly trying and you will get there, good luck.
