I'm in the same boat you're in!! It can be soo frustrating. I'm still having to do lots of purees with my son and he just turned 1. You could try sweet potatoes - mine gagged on that (I think it was the "stringiness" of it)
He really likes yogurt now. Won't eat applesauce, sometimes bananas, he's getting better with cheerios but still sometimes gags on those.
Very small peas were some of the first things he did really well with. For some reason the skin on those didn't make him gag. He really likes beans too. I try to make sure that they are really soft and in really small pieces. He's also doing pretty well with deli meat (Boars Head chicken and I tear it in real small pieces). I think that's soft enough that he can gum it pretty well and get it down without gagging.
Good luck! Hopefully this will pass quick!
