Do I not cut his food small enough?

Ever since Luke started solids he's had an aversion to chewing. At least that's what I think the problem is. My observations are not consistent for all food types. For example Luke will chew and swallow candy. Anyhow here's a perfectly good meal gone to waste despite the lure of dessert afterward. I think maybe I should have cut up that broccoli smaller, or dipped it in candy. I'm still learning.
