Do teenagers regress in their behaviour?

[bookworm9]

Struggling with Dd13 and her behaviour at the moment. Her behaviour is often rude, selfish and disrespectful. This is the case 75 percent of the time nowadays. Difficult to reason with her, and it often leads to an escalation of the row

I think back to a year ago, and it feels like I am dealing with a totally different girl. She was so sensible, mature, kind and I could reason with her so easily. I feel totally puzzled?!

Yes they do!
It's not linear by any means.
Hang on in, and try not to dwell on the lovely child they were, apart from reminding yourself that that person is still inside the grotbag they can be.

Teenagers, like women going through the menopause, or men hitting the mid-life crisis, are all different. Some deal with the changes involved in one way, some in another. And the people around them react in different ways. Sometimes what we perceive as rudeness is a clumsy attempt to find greater independence. Sometimes it really is rudeness. The important thing to hang onto is that the desired outcome is not to get back the little girl of a year ago: it is for her to find the new young adult she is going to grow into. In the meantime, I would clamp down on direct rudeness, but try not to be too reactive.
