I anticipate facing this issue with dd5. She is in the 5th% (she is Vietnamese) and already people assume she is younger than she is, which bugs her. I get that it is different for boys than girls, but my thinking is, she is already going to be prob. the smallest in the class w/out a skip--so it won't make that much of a difference--she will still be the smallest, but at least she will be challenged. (of course this all actually depends on if she needs a skip or not--but I anticipate she will.)
