Hi J.,
Is there anything that you can get her to eat on a regular basis ?
Like maybe applesauce, cottage cheese, yogurt, I know it may sound gross but if you can get her to eat these things all the time then add in fruit and vegetables to them after awhile start giving her a bite of just the vegetable or fruit.
Samething with mashed potatoes mix in gravy, vegetables and whatever meat you are having.
Have you tried oatmeal all kinds of varieties and then mix in the banana, also if you can eat certain baby food 3rd foods stick with them for awhile but also mix in regualer food with it.
I had this problem with my 3rd child when we started him at 4 months eating cereal he didn't like it, wouldn't eat baby food unless I mixed them fruits and vegetables together. Then when we started table food the only things he liked was vegetable soup, corn/corn on the cob, ice cream and chocolate milk and cheese pizza. The only way I've gotten him to eat things is by regularly putting it on his plate.
Now at 6 y/o he eats everything the only thing I have found he won't eat is peas.
So my advice see what you can get her to eat build on the things she will eat. And keeping making her a plate of what you are having for breakfast, lunch and dinner. Sonner or later she will figure out she better eat what is in front of her speically if you start weaning her. As with any child if they are hungry they will eat, mine did and has. Somedays he cleans his plate and other days he picks at everything.
Hope this helps you W. mom of 4.
