I don't have an answer but we are facing the same issue with DS6 jumping into 3rd grade this year. I'm sure that we will face questions. I will wait to follow his lead. Interestingly his K teacher said some of the kids didn't believe last year but DS never questioned it, at least not to us. I hope that DS6 can get it figured out and not ruin it for his baby brother just yet. My older brother ruined it for me when I was only 5, although I choose to continue to believe like Dude described for many years.
