Your reason for holding your kid back in kindergarten is absolutely fine, accepted, and a clear developmental reason. i applaud your decision because it can be a difficult for families. I think the point of the discussion is when parents use it as an advantage for sport or to gain an advantage. I think it occurs more in third grade to 8th grade.

Do coaches and schools really promote this holdback philosophy for sport? Just curious. Is it a bigger problem then it appears?
