Just like to mention that many of us are adults who were grade-skipped (some multiple skips), who have none (or few) of those regrets. There is data to support that the majority of adults who were radically-accelerated as children feel that the benefits outweighed the drawbacks. One's child could as easily say, years later, "if you had only grade-skipped me, I could have..." (http://psycnet.apa.org/journals/edu/82/3/464/)

We make the best parenting decisions we can for our children, and communicate that a) all of our decisions are made out of love for them, and b) we are not perfect, so some of our decisions will turn out to be wrong.

And don't forget that a decision for one school year doesn't have to lock you into all the downstream decisions.
