Tiffany,
You got some great advice here, I just wanted to add one thing. You said he doesn't care for fruit? I got my son one of those mesh teethers, where you put whole fruit in it and you don't have to worry about them choking on it. My son loves it with frozen peaches and frozen strawberries. It might be a fun game to your son! I even put a pickle in it once. Those are the only things I have tried so far but he loves it. It's great for teething too! It's called the baby safe feeder and I got it at Toys R Us, or Babies R Us.
Whatever you do, keep trying! Toddlers are finicky, babies too! One day they like something, the next day they don't.
Good luck!
S.
