Kindergarten is way too young to start travel. Suffolk PAL cannot allow him to play up if there is an age appropriate team for him to play on in your own town. Most leagues have K-1 teams and most likely a combined 1/2 team. Helping to coach/teach the team at this age will benefit you, your son and the rest of the kids on the team. You will be able to push your son and drill him to his abilities while encouraging other boys to play to his level. Get him a lacrosse wall and work with him at home - much cheaper and a lot more beneficial for him. If he is still ahead of his peers in 3rd grade, by all means seek out an appropriate travel team for him but do your research before choosing a team. Travel is a commitment for the entire family and being that he is your oldest child, the rest of the family travels for practices and tournaments as well. Good luck to you and your son.
