UPDATE --
I moved him to 7th grade - he'll be 12 in Nov. He made the 13u/14u high school feeder program which appears to be made up of AA/AAA type kids. Since he's a 12u major player, he's closer to the older kids athletically other than the obvious - physical & maturity. He's hitting 3-9 with 4 walks so far and he's catching - thrown out 2 in 7 chances. One benefit - the feeder team is run by his high school coach so he'll be with him for 6 years (assuming he makes JV and Varsity teams).
To make the transition easier for him (noted here so other parents are aware of this child's processes), he was blessed to play as an 11 yo in many of the top 12u events over the summer - 12u Team USA Futures Invitational, Cooperstown, and 12u MLB/NABC where he was catching the one-in-a-million-type elite kids at that age level throwing 80+ (82 on TUSA gun). And he did a great job.. hit .500 in NABC and .400/.571 in TUSA (nice write up him at TUSA site).

Bottom line, how is the child doing? So far he's taken each step in stride. He's not in survivor mode - he's playing right beside his teammates. That said, mentally and physically he's challenged - last one running sprints, can't hit ball as far as other kids, butt chewings are more personal for him than the older kids, etc.. - but he's enjoying the ride, as he says to us. Will this all change when he's 14 or 15? One belief is that he'll be better positioned as a freshman to handle the senior arms and, when he's a senior, will be very, very comfortable. The flip side is, he'll be the youngest kid in the draft if he makes it.
