Holding back your kid will hurt them more if they get shown up by younger kids. It's something parents should think about before making such a life changing decision for their kid. Imagine your kid doesn't get recruited? Doesn't get into one of their dream schools? Gets no scholarship? Ends up frustrated on a bench once in college... Will it be worth it? Especially when so many will be able to do so without being left back.
Not a parent of a holdback but why do you care what other parents/kids do? Really none of your business. Parents of kids who hold back don't need a lecture. I'm sure they have their reasons and have done their homework.
