When my kids were little, yes, occasionally, usually when asked. When they got older, almost never. They are doing well and I know that, and that's enough. Parents often get competitive about such topics and honesly I just don't see the need to get them all worked up. We pretty much stopped telling school teachers what the kids are up to as well, they won't appreciate and might get defensive as well for various reasons.

At parties other parents often talk about their kids' talent and accomplishments, I just sit there, listen, smile, nod, and sometimes say "that's great".
