An interest in new activities
You might notice she starts losing interest in activities she previously loved and wants to do different things instead.
"My outgoing daughter has suddenly become shy and stopped wanting to do things she used to love, like her dance lessons. I think it's because she feels too self-conscious but I'm not sure if it's coming from her or from somewhere else," says mum Jo.
This is perfectly normal, as Dr Novaes explains. "In the psychological storm of adolescence, taking control (or trying to) of activities that were previously decided for you may feel like a way of stepping up to being an adult and making your own identity stronger. At the same time, it may be a way to control confusing emotional and identity concerns or even impressing a group of friends by showing rebel behaviour."
It can come as a big surprise when your sweet, loving daughter starts having mood swings. Support her through this time of change: be prepared, stay calm and take stock of what she needs from you to cope with each mood.
