She could possibly be ready for more food? You could introduce a 3rd meal. To give you an idea my LOs eating/milk routine -
7/7.30 milk - Normally 5oz
8.15 Breakfast - Porridge
10ish Snack - rice cake/biscotti (if shes awake, which she rarely is!)
12.00 Lunch - Veg/Meat & pudding
1.30/2ish - Snack (As above)
3.00 Milk - 5/6oz
5.00 Tea - Meat/veg etc & pudding
6.45/7.00 Bedtime bottle 5/6oz.
I found she was only snacking on bottles, taking 3/4oz, especially at the 11am bottle, so we dropped it! She now has 3 bottles, & she good sized meals
I struggled to get milk into her at 6 months & still do now! Offer water throughout day too

especially at meals.
HTH, ive babbled...sorry!!xx
