I'm going to try to contribute to this board every once in a while. Lili - not sure what 'normal' should be, but it does seem like your LO isn't eating very much? I've always considered DD to be a light eater (and picky too), but here is what she ate today (amounts are.. of course, approximate):
B: 1-2 oz rice/oatmeal cereal, 1/2 clementine orange, 3 mini wheats, 1/4 pancake w/honey
L1 (before nap): 4 bites rice/oat cereal, nibbled at carrot, 1/4 banana, 1 bite cheese stick, refused broccoli, cucumber, strawberries
L2 (after nap): 1/2 pancake w/PB&J, 2 oz strawberries, 1 oz kiwi, refused green beans
D: 1 oz green beans, 1 oz broccoli, 5 oz pasta w/parm cheese, 3 oz strawberry yogurt, spinach (raw)
It LOOKS like DD eats a lot.. but in reality she just pecks around and doesn't eat a lot of anything.
