My daughter is the same way. She is almost 14 months old (going on 5 years old) and stoped eating baby food at about 11 months. She thinks she can do everything on her own.
She likes the Gerber Graduates Lil' Entrees, which are a little expensive, she only gets a couple a week. She refuses to be fed, she must feed herself. She likes macaroni and cheese, mashed potatos, greenbeans, bread, fruit, the Gerber Fruit Puffs, cheese, pasta, spaghetti-o's, stuff like that. She really doesn't care for meat, if I try to give her some, she will spit it out.
Walmart has these little personal sized pizza's by the lunch meat and cheese section, the crust is very soft. They are microwavable and after it cools I cut it up into little pieces. She loves her pizza.
I too have run out of ideas. My DD won't let anyone feed her so it is hard to think of new finger foods for her.
