Nine month old not eating!

Anyone else having an nine month old not wanting to eat? We started her on baby food around six months. She did great with the stage one baby food which is really smooth. Once we switched to stage two, the thicker food with chunks. She won't eat. The only thing she will eat it puffs and a bottle. I've tried everything. I went back to smooth baby food and that didn't work. I thought since she loves puffs I would chop up some strawberries and blueberries and she won't eat them. Please help!! We don't have an appt with her doctor for another week or so.
