We made the decision for him to repeat, and this year has been phenomenal!! What a joy to know without a doubt that you've done the right thing for your child. This is especially true in this case, because it was such a hard decision to struggle with at the time!
His biggest issue was social...the confidence thing I spoke of above. I suspected that would not be a challenge this year, and I was right. He's been through Kindergarten, he knows what to expect, and he's doing so so so so sooooooo good this year. His teacher is constantly lauding his work and progress, the principal noted in an e-mail how wonderful of an example he is this year, a natural leader in the class, and his papers (classwork) always come back so beautifully done.
Keeping him in this grade one more year was the absolute best decision we could have made for him (which I suspected and wrote briefly about at the beginning of the school year). I thought I would let you know how it's been working out, since so many of you were kind enough to weigh in on the decision when I was struggling with it initially. Hurrah for happy endings!
