Update: DS reports that kids kept asking him how old he is. He told them 5 1/2 but they said, "No, you're not!" and insisted that you have to be at least 6 to be in 2nd grade. His solution? He said, "Oh, I was just kidding. I'm 6 1/2." That seemed to satisfy them.
He told me this kind of sheepishly on the way home from school as if he thought I would be upset about him lying. But I said that how old people are isn't that important, so if he wants to tell them he's 6 1/2, it doesn't matter to me.
I don't know if that was the right thing to say or not, but it seemed like the right thing at the time.
