I know what ur goin through. I have twin 16mnth old gurls, and let me tell you one of them was eatin soooo much when she was 8 months. But dont worry, have u tried givin her juice? that might also help cool down on the bottles of formula and that will fill her up a little much more. I myself would bring the bottles down to about 2 or 3 a day of formula and about 1 or 2 bottles of juice.. only 4oz, and dilute it to where its like 4oz of juice to 1 or 2 oz of water. that would help too. Does she have teeth yet? if she does, start givin her some table food. only a little cuz it can really mess with her stomach if u give her too much, i started my gurls out wit a little bit of mashed potatoes, and some pies. but very little of it. But i know where ur comin from cuz my dads side of the family is big and so am i, but once she gets a little bit bigger and is able to walk she'll start to burn off the weight. but everything should be fine. Also if she has teeth, start to feed her some stage 3 foods too, dont give her too much just start her on it. I was giving one of my daughters stage 3 foods at like 5mnths old, cuz 1 n 2 wasnt enuff, hehe.. so yeah i kno what its like.. i hope this helped..if u have anymore questions just email me ok..byes
