Baby chokes on everything (update)

Okay ladies I’ve come here before with the same topic but today we went and saw the pediatrician. She said that we would do a swallow study and she would send her to therapy. I’m really nervous and don’t know what to expect. My baby is 9 months old and is still using medium flow nipples. She chokes on most everything I give her. Eggs, bread, things of that nature. She does okay with her stage 2 baby food but won’t finish a whole container and pushes it away. I only give her small bites because she will gag. She also gags herself with her fingers multiple times a day. Has anyone else had this problem? What should I expect from the swallow study? What could be wrong? Thanks in advance ❤️

**she is growing well and is gaining weight. Dr said she’s not concerned with nutrition but she should really be eating more of what we are**
