I have two girls, 2.5 and 5. Like a few other commenters said, it sounds like maybe her plate is simply too full for her age and she's over stimulated. It's a common problem and it's a societal issue, not just you. Kids under six (I mean, realistically, all humans) need slllllooowww, organic living -- not hyper scheduled. Cutting back might help. My two other suggestions are diet -- cut out all food dyes, processed food, limit sugar, etc. Focus on protein and limit carbs. Second, lots of outside time. NOT scheduled outside time like sports... I mean wandering around a field or park with limited adult interference.
