How much formula?

[milkmoustache]

DD (10 months) has been gradually - but decisively - been dropping breastfeeds until she is now down to just two, first and last thing. I don't really know how much formula to offer her. She is a great eater and always has 3 solid meals a day, plus water from her beaker, but looking at the literature I'm sure she needs more formula. Since she was exclusively BF for as long as she wanted, I'm a bit unfamiliar with formula amounts etc so could really do with some help here...
She is perfectly happy with a bottle but I just don't know how much/often.

its normally around 20 ounces of bm/formula per day from 6-12 months which is inclusive of milk with cereal, in foods, dairy products, etc so they dont have to take it all as a drink. At this age my dd had 2 bottles a day which were morning and evening but she did eat cheese sauces, yoghurt, etc too

By a year ds was down to just 2 breastfeeds am and pm. Between 6 months and a year he had first 2 , then 1 8 oz bottle during the day. However at 10 months I doubt your dd needs to have it introduced now, as long as she eats calcium-rich foods such as yoghurt and cheese and drinks during the day.
