Baby eating solids

My baby girl will be 9 months on the 8th and she's not big on solids when I do try to feed her one her the day she gags and it's hard for me to even get halfway done so she drinks milk exclusively. She has interest in our food but only if we feed it to her how do I get her to learn to grasp it and put it in her mouth she just lives it up with her hand then lets it go or throws it. How do you full time Mom keep up on the solids when they're this little my husband just feeds her milk during the day and I try to do what I can with dinner but just use baby food. Any help would be appreciated
