I don't lie about age either. I'm also ready to *fight* with someone to have my child admitted to a progam that is appropriate fo them even though they are younger than the stated age requirement.

I've even gone so far as to literally yell at the director of a program and accuse them of age based discrimination, although we ultimately decided that the program wasn't worth the aggravation.

Which brings me to my next point, I've found that if a director of a program doesn't understand what I'm talking about when I bring up age based discrimination then chances are, the program probably won't meet my child's needs anyway.

Another good reason not to lie, if I'd lied and enrolled my child, I'd have found out the hard way(on my pocketbook!) that the class wasn't a good fit.

There are programs out there that say YAHOO when you say your six year old loves (fill in the blank) that normally only 7/8/10 yo do. Those are the places you want to be.

In terms of others taking notice of your child's abilities at a young age, I agree with the others. Smile, thank you, change the subject. I think it's also in good form to compliment their child on something.
