My son skipped mid year from 1st to 2nd and is now going into 5th. He is taller than most of the kids in 5th so we don't get many questions now, but they do still come up occasionally. I prefer the blame and dodge method. It goes like this "Oh my husband met with some people and it just all came out that way. Can you pass those delicious cookies?" Despite the fact that my husband was only in the meetings to be the "suit" and really just nods and agrees with me :-)

We have gotten the blame of anything he ever does wrong is because of the skip. Again blame and dodge "The doctor/principal/teacher/psychologist/grandparent/other adult says it's totally unrelated. Can you pass those delicious cookies?"
