Dad's always been a huge eater - even at 98. Recently he seems to be trying to chew everything into a liquid, which doesn't really work with meat. One bite might take 15 minutes. He gets tired before he can finish. Should I start pureeing everything? I hate to do this since eating seems to be one of the few things he still enjoys. A few months ago we started with Thick It to nectar. Since then he hasn't choked. But he's never choked on solid foods. Has anyone else had experience with anything like this?
