DD started y7 3 weeks ago. She loves it and has made a good group of friends. She’s mentioned twice though that she’s walked past 2 fights in the park next door on her way home between girls in her year (2 different girls each time, both fights broken up by teachers). Is this usual for secondary or have I sent her to a rough school? She says everyone behaves well during school and she feels safe, but I do worry! Will it settle down?
