My ds was generally a really good eater, taking a wide range of food very well. Over the last 2 weeks he takes a few bites and then gets hysterical, making mealtimes quite frustrating all around. Switching to yogurt with fruit compote gets him to gobble down a bit more, and then hysterics again. Any ideas? His top teeth just popped out- is there a link? Just feels like such a downer when I'm spending so much time making fresh food that gets dumped, and I worry he's not getting enough.
