Have you tried offering him cold things too? To help with the teething pain while chewing? Things like frozen waffle sticks or yogurt bars etc? Sometimes the harder things like the biscuits etc. are too hard to start with when introducing the concept of chewing.

Another thing that I have done is to sneak a few "chewables" into the soft food. Like putting a cheerio in a spoon of his tapioca etc. Sometimes the mixture of both helps to transition to the harder things to chew. He likely will spit it out, but eventually he'll chew it.

While I do agree with keep offering him new things, I wouldn't introduce too many new things. All the changes he has been through, food is the only thing he can control. While it's a food "issue", it's also about what makes him feel safe and in control with all the changes. I had a "squirrel" eater...held food in the cheeks of his mouth. And he was picky too...with not having had much variety. But the variety scared him, so for awhile, I only introduced a couple new foods a week really, to ease him into it.

I also gave him pediasure or smoothies to make sure he was gaining weight and getting the nutrients he needed while going through this food battle.
