Mealworms are no good for any age dragon. They have hard to digest shells and not much meat. Superworms are ok, but not for under 15". With a baby, you're going to want crickets, and tons of them. You should let them eat as much as they want 3x a day for 15 minutes, and that can add up to nearly a hundred crickets every day (Yes, I know he's small and it seems impossible, but trust me, it's very possible, I watch mine do it every day and she's only as big as a 6 month old should be).
