How To Get Your Toddler To Eat

My now 22 month old is a VERY picky eater. The things she used to like before she turned 1 she now does not (I know this happens). However, I feel she is not getting enough. What she does eat, she doesn't eat a lot of. She is only starting to eat "real" bananas and strawberries (she still eats baby jar fruits) and NO vegetables (again, only from the jar). She is also wanting her milk from the bottle, and will only drink it warm. She does use her sippy cup for juice and water, however. Please send me suggestions on how I can help her get the nutrition she needs!!
