10mknth old food portions

how much does your 10-12 month old eat? my daughter eats a ton! just now she had probably 3oz of steak 2oz peas and 2-3 oz of fettuccini alfredo..... last night probably the same amount portion of chicken, zucchini, spiral pasta... for breakfast she'll eat a piece of toast and banana etc.. she eats a lot. plus puffs through the day and teething biscuits. if she sees food and i'm about to grab it she'll snatch it abd try to store it in her cheek s lol... she is only drinking about 12-16oz of formula a day...she is 20lbs and doctor said her weight is fine compared to height.... any one else have this? i tried to cut her portion down one day and it was MISERABLE.
