Hi A.:
My son is 9 years old, but will be 10 years old in May. My husband and I are both quite adamant that he not be moved to an upper division for several reasons, namely: 1) he is not ready, though his baseball skills may be comparable to those of older boys, he is not emotionally nor intellectually as old as the "big" boys (the stuff they chat about on the bench during the games is surprising and I know this because I have an older son, as well)...2) his little body is not ready, my son is quite small for his age and though baseball may not be a "contact" sport per se, I've seen enough accidents to know that it can be and little bodies can get seriously hurt when big bodies fall on them...3) the league is doing it (in our case and many other cases that I know of) because it is hard to recruit bigger kids than younger kids. Sadly as kids get older many (thank God not all of us) parents tend to not be as involved. That is not a good reason. While I understand that Little League is a "business" I feel that it is our business as parents to do what is best for our kids and a need for more kids in the upper decision is not a good enough reason in our case...and finally 4) kids need a season where they are the STAR of the team, where they are the best at what they do and are lauded for it by their team mates & peers. I know that one more year in the lower division will help our little guy's ego tremendously and this confidence that kids get transfers over to the rest of their life (acedemics, personal relationships, etc).
These are our reasons, of course it is a personal decision and being the great mommy and daddy that you and your hubby are, I know that you will take some of these "thoughts" and make the best ultimate decision for your little guy...
Best of luck and enjoy the season!
