D.P.
I would not worry about your 2 year old getting obese if she eats healthy foods. I think most of our generation's obesity issues comes from all the high fructose and partially hydrogenated ingredients in most pre-made store bought items...not to mention fast food items.
I doubt there's many people that ever got fat from eating fruits and vegetables (reguardless of the amount). It's all the stuff we like on our fruits and veggies that put the pounds on. It's the butter, gravies, sour cream and things that put the fat in us.
Every good diet should say you can have your fill of fruits and veggies. Of course with kids you do have to limit the fruit a bit. Encourage her to eat healthy but be sure you don't put the fear of being fat in her at an early age! That's an entirely new set of issues that diets don't fix! lol
Congratulations on such being blessed with such a healthy eater! I hope she continues loving healthy food!
