I was the youngest in my high school class and was hurt athletically, by not being held back, entered kindergarten at the early age of 4 years old. The older kids in my class were almost 2 years older than I was. From Kindergarten to 9th grade, I was easily the fastest, most athletic athlete, but I also entered puberty much later than average and by the 9th grade, I was easily passed by, in speed and size by much more mature boys. As a result, I held all 4 of our kids back, from kindergarten, by 1 year, who all had fall birthdays. 1 girl and 3 boys, they ended up being some of the older kids in their class, best decision I’ve ever made.
