My gorgeous just about to turn 13 Dd is having vicious mood swings, tonight she lost some homework on my work laptop as she hadn't saved it, & this was my fault of course. She gets really nasty and cannot see that her behaviour is unreasonable , then after some sobbing & threatening to phone childline she turns back into my lovely girl again. It's exhausting ! I try so hard to keep calm but don't always manage it, someone please tell me this isn't how it will be for the next 5 years !!
