It’s true that teenagers are especially prone to mood swings. This is often put down to the surge of hormones produced at the start of and during puberty, but there might be other reasons too.

The hormones involved in puberty work like this: a group of hormones are produced by the hypothalamus, at the base of the brain, and levels begin to rise about a year before you start noticing any physical changes. These hormones basically kickstart the puberty process.

Is there something bothering her?

Is it possible that there is something behind your daughter's snappiness? Could she be worried or pressured about something? Ask her if there is something troubling her. If she wants to talk to you about it, make it clear that you are always willing to listen to her. Remember that adolescents can be very secretive and withdrawn, so don't feel rejected if she doesn't want to open up to you. Take time out together to talk.

Don't take it personally

If she's having a bad day, the family is the most available target for her frustration and anger. Try not to take it to heart. Blaming parents can be an easy way out for an adolescent who's having a rough time. Empathize with your daughter - many of the changes that she's going through are things that you've experienced yourself, though she may find it hard to believe.

Take a step back and try not to overreact. Arguing back, shouting or criticizing her only makes things worse. You may feel angry but avoid rising to the bait. Let the situation blow over until she cools down. If you find her behavior unacceptable, discuss it calmly later.

State your case

The family is an easy target, she knows you will still love and accept her even if she loses her temper with you. It's very likely that outside of the family, your daughter controls her temper and is far more easy-going. It's not unreasonable to expect her to exert some control over her temper at home and not excuse everything because she's a teenager.

Explain the effect that her moods are having on the rest of the family. Tell her that although you understand her situation, she is still part of the family and if she shouts and snaps, it makes the atmosphere unpleasant for everyone. State your case; say that you expect her to show more control and not lose her temper so easily.
