Just keep it interesting, catching fish any size keeps them interested or tadpoles, bugs etc. I have been guilty of trying to catch bigger fish and getting skunked with them, u know u wanna wow them, but they don't care. For blue gills or sunfish I use pieces of worms or Berkeley crappie nibbles. If we try for bass like today he uses tiny cranks, poppers, swim baits and grubs. He only recently started to recently use worms and he really does what he wants, when I said his version of shakey head,I meant it, he had that thing rocking but it got bit. He uses a small spinning reel, on a 5' zebco rod. Patients helps too there will be tangles. Oh one of the biggest things is use a snap, I never used a snap at first but now I do, doesn't make a difference fish will bite, he had one on today. It makes lure changes easy.
