My 2037 (negative two months old as we speak) will simply be started late. His birthday would put him class of 2036. But having learned from mistakes with the others we will hold this one back right from the very beginning. As long as May 1 remains for some mysterious reason the cutoff for baseball. Youth ball should however just sync up with high school. Bottom line is it right to hold back? What does that even mean? Right and wrong are so obscure. Does it give your kid an advantage? You bet. Since I am in the business of caring about my kid more than yours I am holding him back!
The knew trick will be keeping them in the womb for a year longer and growing. Sell that to your wife.
