If you want to drop one, you could probably think about the lunchtime one first of all as that would fit into a nice 4h EASY-type pattern (7, 11, 3, 7). Until 12m, milk should be LO's main source of nutrition, so if she seems happy and content with feeds spaced that far apart, go for it. If she's fussy and seems to still be hungry, she may not be ready to stretch out just yet.
