I sure wish there was a way to bring up this research with my judgemental "friend" who redshirted her kids and takes every opportunity to tell me that they have been given the gift of time and that I have made decisions for my kids that she thinks are just plain wrong. Unfortunately, she, like a lot of people, believes what she believes and there is no research in the world to convince her otherwise. Although I like the head-cocking, "That's what I used to believe . . ." approach of Grinity's!
I figure that time will tell and the success of my kids will someday prove that "the gift of not wasting time" was the right decision for my kids. And until then, I try to avoid getting into conversations about education with anyone not in our situation. Thank goodness for this board!
