How long is she going in between bottles? If she's getting 7 bottles a day, even, she's getting a bottle about every 2-3 hours, which is way too short of a time between bottles for an 8 month old and why she's getting way too much formula during the day. She should be drinking 32 oz. MAX. of formula per day and should be able to wait at least 4-5 hours between bottles. If you increase her solids significantly, space her bottles out more, give her solids in between, she'll have a much more well-rounded diet. By 8 months, my daughter was eating 4-5 oz. fruit plus 1/4 cup cereal for breakfast, 4-5 oz. veggies and meat plus 1/4 cup cereal for lunch and 6 oz. veggies/fruit and meat for dinner. She nursed no earlier than every 4 hours. While your daughter might not eat as much as mine right away, I definitely think you should increase the amounts of solids you give her per sitting, increase the time between bottles and decrease the amount of formula she's drinking per day. If you're worried about her being thirsty, introduce water in a sippy cup at meal-times, so she can start getting used to the idea of drinking from a cup now. Your pediatrician will probaby tell you the same thing at your 9 month appointment.
