mashed food trouble. please help!!

We've been giving our daughter oatmeal cereal  and stage 1 & 2 foods (all are Gerber) since she was 5 months old. We decided to start transitioning her to other foods since she is 8 months. We mashed some bananas and she SCREAMED. She loves the Gerber bananas, but won't eat the real deal. We have also tried the puffs and yogurt drops for the last 2 weeks or so, and she hates them. I tried mixing real bananas with Gerber bananas and she still got really mad. Is this normal? Does anyone have any suggestions?  I feel like she will never want real food! We are going to test out real oatmeal and see how she does. Please help!!
