Becauyse dh and I don't. We are very proud of dd1 of course and try to encourage her as much as we can without being pushy. All our daughters are amazing - we don't need the G&T label to know that! I just don't feel the need to tell people - and I couldn't in any case find the words to do so without sounding boastful!
Part of me thinks that maybe I should be more publicly effusive about it though - what do others do?
