At 9 months I was still doing 4 feeds a day but at 10 months dropped to 3. I don't think Carter necessarily wanted to but I was doing it in preparation for going back to work. He adapted very well though and hardly missed the feed after a few days. I found that the morning feed (after his am nap) was the easiest for me to drop first as that was when I just gave him lunch instead.
If your lo seems to be losing interest (like taking shorter feeds or playing around rather than drinking) then she might be ready to drop a feed. I would say as long as she is taking in a good amount of solids and she has adapted to a bottle or sippy then you could go ahead and drop a feed. However, if you are in no hurry and your lo seems content I would keep on doing what you are doing!!!
I will definitely be sad the day Carter decides he's done!!
