DD in Y7. Our relationship is OK but I have to work at connection and have an eye on the teenage years ahead and wanting to keep channels wide open. She sometimes chatters and shares if she's in the mood but often real worries only emerge months after the event so I know she bottles things up and hides things. She had a chatty evening yesterday and told me her friend has a date and asked me not to tell the mum, who I'm friends with. All sounds dead innocent, a kid in the same year, just a walk in the park after school. I still feel that the mum ought to know but am rueful about betraying DD's trust. I am thinking I'll tell the mum, ask her to be careful with the info and have a chat to DD about good and bad secrets. I feel like she probably told me as she was a bit unsure herself what to do with the info and didn't feel right keeping it in. I'm seeing the mum later and won't have a chance to chat to DD first so wondering whether to wait and tell her over the weekend when I've chatted to DD. WWYD?
