I feel the same way a lot of the time! Keep in mind that toddlers have really small tummies and burn TONS of calories. Most of them need to eat every couple of hours to keep going, which usually means 3 meals and 2 snacks. That said, watch her cues. If my DS had a snack, he would never be hungry for his meals, so we dropped them before he turned 2. My DD, on the other hand, would eat a full meal every hour if we let her (hence, why I also feel like I feed her all day long!). Sometimes it helps to do snacks on the go, like give her crackers while we're grocery shopping, which also helps keep her entertained.
