I weaned E with she was 24 months so slightly older but it still should apply. I stopped both feeds at the same time but started in evening. So in the afternoon I told her that Mummy had no more milk now and that she was such a big girl now that she could have milo before bed. So i gave her, her milo after her bath at same time she would normally have a b/f and made sure that I gave her lots of cuddles. Then when she woke up early the next morning (5am) asking for a feed I reminded her that mummies milk was all gone and after a quick cuddle she went back to sleep and then she had a drink of milk with her breakfast at 7.
And that was it....after that she asked a couple more times and was perfectly fine when I said no more milk
I liked I could explain it to her and she understood- made it heaps easier
