Lol, nope I don't think that's a lot at all. My DD would give her a run and then some. Most days she eats more than me, but at over 120cm tall and only 20kgs, she obviously burning it all off.
At first I was worried, I tried worming her just incase too, and have tried restricting food, but she just ends up a seriously cranky cow because she's starving. I do tell her on every second request or so to go and have a drink of water though.
Then there are days, albeit few and far between, that she hardly eats anything.

Eg here's yesterday's intake
Pear
Bowl porridge
Toast
Mooring tea but I can't remember what
Bowl of salmon mornay
Nate's leftover spagetti tin but he only had 2 mouthfuls
2 rice crackers
Few homemade bikes
Apple
Butter chicken and rice with 2 serves of rice
Watermelon and a Vickie for dessert
