11 month old baby weight?

me and my husband are average weight people... me - 135 ... him - 180ish. my baby girl was born 8lbs 14oz, and ever since then i am so sick of the comments! the majority say, awww what a healthy cutie pie, but a lot of the time i get... wow, such a cutie, she is a bigg girl!! thanks i guess. she weighed 22lbs at 9 months, id ume now she weighs 24-25lbs. however, she eats half the amount of normal 11 month olds! i give her about 18-20oz a day and 2 meals. (gerber website says i should be giving her 35ish oz of formula and 3 meals? wow) im just wondering is this ok from all the moms out there? she is such a sweet happy go lucky baby, i just wanted to connect with other mommies, since this is my first!
