I have learned not to talk about it if at all possible. If pressed I will say the truth but keep it simple and if whoever asked the qeustion feels uncomfortable she should know not to press me again. Sometimes when other moms talk about their kids' achievement, I make general comments but don't say anything specific about my kids. I've met one mom who actually went ahead to "test" my son his reading level (she pulled him aside in the classroom during a party), which was so inappropriate. For these really competitive moms I even had to go out of my way to make sure they don't see what my kid is doing so that their kids don't get too much pressure.
