J and J:
We stopped gradually, as I put my DD to CCC, and I breastfed only before and after CCC. By that time, my girl was 18 months and she slowly weaned off in 3 months. As we started to expose her to various solid food at night and gave formula milk in her CCC.

Me too, only bf in the morn & night (she still stirs at night & ask for milk as we co-sleep). but i am keeping my supply higher, cos she still takes a bottle of bm bet lunch/dinner w small cup. she simply refuses to use the milk teat.
my 1st drop will be changing the milk feed bet lunch/dinner into fm. that is like 'no impact' to her & she eats proper porridge/rice lunch/dinner too.
nw that she will pretty big, she will ask to latch & she seems keen to continue
