I don't think that pre-schoolers or even K students associate Valentines Day with romantic love. It's just fun for them. They get a card and some candy. Life is good. It's the adults who are over reacting and reading all sorts of things into what to the kids is just a fun day.
I agree, which is why I don't think it is a big deal whether the day is called Valentine's Day or Friendship Day, or Tuesday.
Now the other issue that has morphed out of this thread - fostering non-competitiveness, I do have to agree has been taken to a ridiculous extreme.
Last year I was in charge of my then 4yo son's preschool Christmas party, and I was told to only have "non-competitive" games, no musical chairs, no pin the tail, etc. unless I could find a way to make everyone win.
Well I did, as a matter of fact, and fun was had all around, and the kids were little so it didn't really bother me. But when the same request was made for my 4th GRADE daughter, I had to roll my eyes.
A couple of years ago I read an article about a rash of suicides among college freshmen. One of the theories was that these young people, having spent their childhoods encouraged, promoted, and exalted, could not handle the pressure of a university system, where there were thousands of students, each just as "special" as the other. Without constant reinforcement of their own worth, they could hardly function.
Well, that's just a theory.
But it bears considering. My 9 yo dd figure skates, and she competes with girls at her own age/skill level. She works hard in preparation for a competition, and she wants to win. I used to tell her "just do your best", but one day she came back with "but what if someone else's best is better than my best?"
And I had to admit, that in fact, that is the way life goes sometimes. You do your best, and you still don't win. And it's disappointing, and it stinks, and there are no platitudes to make it feel any better. And let's go have some ice cream.
