Ds has just turned 11. He goes to a skating club and has taken a shine to one of the coaches daughters - she's just turned 9.
Ds says she's his best friend etc, she's the only friend he's ever wanted to get a birthday card and present for. Ds is a young 11 and she's an older 9 but I'm not sure if their friendship is appropriate given the age difference. What do you think? Or am I over reacting?
