I agree with everything said, taking time off or a little time away is a good thing. I would even suggest planning to take a weekend off during the season.
Another factor sometimes is that kids get tired of having expectations placed on them every weekend. Some kids are delivering the message that they've had enough of the "stress."
But two days before Districts is really tough timing. If you would have known this two weeks ago you could of planned a weekend off! But now all you may be able to do is remove as much stress as possible from the kid.
And to give deanstraus a little break, "why are things always turned around of the parent?" Because the parent/coach is responsible about 95% of the time.
Good luck to you and your son this weekend!
