I know how you feel, my son did not swallow much whatsoever until recently at 14 months. It was quite exasperating because everyone kept telling me, oh he will get it, and frankly he did not.
My situation is different because he had a physical reason why he could not eat solids that we had fixed. (tongue tie) Have you discussed with your pediatrician what is going on? I would recommend your first line of defense is to bring in a few examples of food and show your pedi what your LO is doing. It's worth it to get a medical opinion if the behavior is normal or not.
If your LO is having a serious aversion to textures and will only eat puree, (and only puree at times) then there are things you can do to help. I would certainly look into this with your pedi.
On your own, the only thing that you can do is to continue providing a variety of textures and tastes that your LO can explore. Offer both savory and sweet, and soft and crunchy foods. Perhaps your LO is simply super picky on foods. I would certainly also give more finger foods than the 'O's. You can give your LO what you're eating, and if the food is very spicy just don't spice a bit of it as much and you should be okay.
Oh one more thought. Don't assume that your LO has the same tastes that you do. I learned that the hard way!!! I'm not a meat eater, and I assumed that my LO would not be either... but it turns out that protein is his favorite food group. He just adores shredded chicken, fish, turkey, and pork although the pork is harder for him to try and chew up.
Hang in there and it will improve, you just have to figure out what's going on and find some things your baby likes to eat!!! Trial and error is sometimes the only way you can figure these things out.
Good luck momma.
