First time poster and I would love some advice regarding grade acceleration for my DS who is only 1 year younger than my DD. DD is HG and DS is PG. DS is about to enter 2nd grade and I know that he should be at least going into 3rd otherwise he will be bored and will continue to say "why do i have to go to school? it's boring". My DD is going into the 3rd grade. She loves school, so she can be content with outside enrichment programs such as CTY.

Question: Has anyone experienced a grade skip where siblings are consequently in the same grade? How did it affect the sibling that did not skip?

Thanks in advance for any insights.
