I personally would let him go, but ask the other mom both to make sure
he gets time alone if he gets cranky, and also to let you know so he
can come home if he gets too homesick. But DON'T tell him that
because I think that will mean that you expect him to fail.

Actually, he can't come home if he gets homesick. Only in an emergency
would we drive that far away to pick him up before the trip was over.

I feel more inclined to let him go, but my DH really doesn't. I feel
my DH is overcautious and too loathe to let go (he didn't want him
going on overnights until he was 8 -- he's our oldest), but the fact
is that I don't want to force the issue and then have my DH spend the
week feeling extremely nervous about our son. The issue of missing him
is one I think we would have to accept; it wouldn't be fair to prevent
him from doing something good for that reason alone. But my DH just
doesn't think he should be away from us for that long, that far away,
at that age. I will talk to him one more time about it today, but if
he still feels "no" as a gut reaction, I guess I'll have to go with it
even if I don't quite agree.
