Up until two months ago dd was great, excellent at school, lovely all round. Hormones seem to have kicked in and her attitude is going down hill. The biggest issue if that she seems to be constantly lying! Stupid things like saying she didn't have some make up on when she clearly did and not admitting it for ages (no big deal it was a weekend and she wasnt going anywhere, she had just been experiementing) lying about going to bed at a certain time, lying about something her and a friend did. This morning I've just found out she has lied about sending a text. I can deal with the mood swings, etc but I desperately want to nip this lying in the bud. Aibu to go ballistic, cancel her friend coming over at the weekend, take all electronics off her and cancel a guides camping trip she's due to go on. This is the fourth incident of lying in the last week. Is this normal?
