I can not think of any good reason to be the youngest in the grade…athletically, socially and academically. If your child is academically advanced, he can take more Honors and AP classes to challenge himself and look better for colleges. Athleticism and intelligence may not improve by age, but he will have more confidence. A win win situation. Give him the gift of time.
How about...that's just when his birthday fell? Someone always has to be youngest, someone always has to be the oldest. I guess I am just not that in tune with any reason to hold a kid back other than it has been recommended by doctors and/or school personnel due to a deficit the child has shown in his development.
And yes, my son is one of the youngest. 23 days younger he would be in a different grade.
