re: Coaching T-Ball for the first time. Suggestions?

Figure out who your best fielders are and put them at pitcher, first base, and shortstop. Keep the ball in their hands as much as possible.

If you don't have a first baseman that can catch a throw then swallow your pride and have them roll the ball to first until they can catch a throw.

RF is for the kid that plays in the dirt or chases butterflies.

Make sure they know how to run bases.

The rest sort of takes care of itself.
