I think that's the right amount. My DD was having about the same in FF at that age. My DS is 9 1/2 mths and is having 6-8 BF's a day. Obviously I can't tell the amount he's drinking but the frequency is usually 6 is feeds a day/night, plus breakfast lunch and dinner (solids) and sometimes one or two small snacks. Milk (formula or BM ) should still be his main source of nutrition until 12 mths.
