This is starting to really wear us down. Our oldest DD (7, nearly 8) is just so bloody loud. She doesn't shout in anger or frustration, she just seems to have a volume button stuck on MAX. Her hearing has been checked and it's fine. At school she's absolutely fine, although sometimes she might call out an answer rather than raise her hand etc but otherwise her teacher absolutely loves her.
Friends have noticed this (that she's unusually loud) so I don't think we are imagining it or Victorian in our attitude towards kids. Her younger sister (4.5) is no shy wallflower but still doesn't make anywhere near as much noise as her older sister.
Any suggestions on how we might be able to change this? Is it excessive physical energy? Even after busy day outs, she can be like this. And I've been at bus stops with her and other families, and she just makes so much noise while everyone else seems to wait mostly patiently and quietly.
