We had a similar feeding routine to you at 9 mo and I think it was around 10 mos when we dropped the am 'snack' bf, mostly because L just wasn't interested in it any more when I offered (she'd rather be playing).
I replaced it with a small snack. Something like raisins, rice cake, fruit, bread stick or cheese. Also offered water with the snack (from a cup).
If your LO is generally eating well though and seems to still want those bfs (or you're happy to keep offering) then I don't think you need to be in a rush to drop any day feeds. Milk is still the most important thing until they are 1 yo.
