hi, the only thing i can suggest is to maybe eat something soft infront of him, and over-exaggerate how DELICIOUS AND GREAT it is...and maybe he'll seem interested, then you can offer him a bite. this works with my daughter. i would suggest something like a bannana, maybe a peach, or even a tiny piece of watermelon, even if he just sucks on it to taste it, and doesn't actually eat it, at least he's trying. we've noticed that lately our daughter doesn't want to eat anything she can't feed herself with her fingers, so there's alot of foods we can't get her to eat...and we just go "crazy" over how great it tastes, and once she puts a piece of her food in her mouth, and her mouth's empty, we sneak a small spoonfull of what we want her to try in. if she likes it, she lets us get a spoonful in here and there inbetween what she's feeding herself. it seems that maybe that's what your son wants too, to feed himself, since he ate the puffs. i would also suggest getting the dried fruit, or maybe the little fruit bars, or breakfast bars. they're soft, and if you break off pieces, he can feed himself, and it won't make as much as mess as just giving it to him to do what he will. all these snacks have i think at lease 99% all real fruit in it, so they are nutricious. good luck, he'll start when he's ready, just keep trying something new every week.
