M.E.
He's way too old for jarred baby foods and is trying to tell you so. Buy a bag of frozen vegetable, mixed or maybe peas. You can also buy it in a can. Put some on his tray in his high chair(defrosted, although some babies like the frozen stuff whe they are teething). You can also buy canned fruit and cut it up. He can chew all of this stuff. He does not need teeth for it.
