First question I have is how many teeth does she have? If she was a late teether, she may not be ready for bigger solids yet. also, at what age did you first itroduce solids. my son started at 3 months, but if you didn't strt until 6 months, she may need a little more time to master the first part of this skill.
Now, what I recommend is trying things that bacically fall apart in her mouth. My niece LOVED egg noodles boiled in chicken broth. Her mom would boil them until the would practically fall apart when touched. You can also put things like small bites of banana or soft avocado on her high chair tray while you're prepairing her food. You could also provide those Gerber veggie/ fruit puffs this way, Cherio's, peeled and quarted grades, or even some left over baked sweet potato bites. This way you are giving her something to do while you prepare her meal. Even if she just plays with it, you're still adding skills to her mental tool box.
You can also try those "My Safe Feeder" or something like that with sweet fruit pieces in it. They are mesh bags with a handel that you can put things like a slice of pear that she can hold and chew on, but all that comes out is more of a pear pulp. She is learning about texture and consistancy, but can't really choke on it. My son STILL likes getting ice in these, and he's almost 2 1/2.
Hope you find something that works soon, but don't let yourself get stuck on what's "average" for her age. She just may be very pick about textures. My MIL says my hubby would only eat BLENDED Chicken soup, tortillas, and cereal until he was nearly 12... YEARS! I think (HOPE!!!) this is a little exagerated, but it does happen.
Take care, and contiue to ROCK as a Mama! -J
