doesn't want bottle anymore

My daughter is 7 months. She's been doing really good at eating solids. She really only wants to feed herself, so puréed foods is difficult to give her. She does really well with foods she can grab herself. But now she doesn't want a bottle. She used to eat 6oz and now she will only eat 3 oz at a time. But will take solids whenever offered. I have tried bottle first before solids, and everything. Anyone else going through this? Is this just common?
