Baby practices for K-1 Lacrosse? Step and offer your help to coach the team. Clearly you are over qualified and your head coach would appreciate the help. Ask to have your son play up next year. PAL and your program can allow it. Whether they do is up to your prodigy. Safety is #1 concern. Obviously this is your first son. Paying for travel for the next 10 years is too expensive and there are no pure 1st grade teams. Most tournaments and programs don't start until 3rd. I guarantee by high school nobody will care if he played club ball in Kindergarten.
