ok Im going to try to answer this with how much Kaydee eats (you will see Kenzie is just fine lol)
6:30 am-- 5 oz bottle
8am-1 stage 2 fruit OR 1/2 stage 2 fruit mixed with cereal
10:30 am-- 5 oz bottle
1pm-- stage 2 veggie
4pm- 5 oz bottle
6pm--stage 3 jar of meat/veggie (yes she eats the whole darn thing!)
8:30pm- 6 oz bottle before she falls to sleep
so she is also taking in about 25oz a day, and about the same amount of food. She also has the teething biscuits 2x's a day and usually pieces of waffle at breakfast, and a little of whatever we eat at dinner time. Only difference is Kaydee SCREAMS for her bottles

She also will not fall to sleep unless she has one, so she is usually very tired while drinking them. I would say for now, keep up with the formula as long as she will take it.
