Same ole' - Same ole'

Not much has changed in what Jeannette is eating.  It's the same thing day in and day out.  I still try to introduce different things, but nothing seems to have stuck.  I still go back to the question of how long is this supposed to take for her to change her palate?  Months, years?  I just don't see it happening.  I still struggle with the fact that she can't eat certain fruits that she used to like to eat: bananas and oranges for example.  Because they are so high in sugar, she shouldn't eat them.  I also keep arguing back in forth in my mind about these fruits.  She's not getting enough nutrients from anything else, so why can't I feed her a banana?  Is she never going to be able to eat a banana or orange again in her life?  Will we have to be tiptoeing around everyday about food?
