When Zane is getting full and isn't very hungry anymore, instead of not accepting a bite, he opens his mouth, takes the food, but then just doesn't chew or swallow.  Today he did this, but wanted down out of his high chair.  I got him down, but thought that he had better chew and swallow before I let him run around because I didn't want him to choke.  So, I had him standing on my lap facing me, and was wondering how I was going to get that food out of his mouth because he wasn't doing anything with it!  Well...he sneezed!  And I had a half chewed pea, small bits of macaroni, etc, all over me!  Problem solved!
