More Calories For A Toddler?

I need to boost the calorie intake of my toddler (per the pediatrician request). To me, she's just a typical toddler in the way she eats; not exceptionally picky, just toddler picky. She doesn't like cheese but I can get her to eat more with a dose of ketchup or peanut butter on stuff.

We're going to the nutritionist soon and I don't want to be told to just load her up on pediasure (I have a BIG problem with pushing calories on a child in the form of sweet stuff). She'll be 2 next week and is about the size and weight of a big one year old.

Any advice?
