My daughter will soon be 16. She regularly speaks to me in a very rude and disrespectful way.
She also winds up her younger siblings (aged 10 and 11). She teases them, calls them names and sometimes pushes them in a playful but provoking way. She tends to do it quietly or subtly, so it often isn't obvious to anyone else.
If one of them eventually reacts or says something back, she'll immediately raise her voice, shout at them to "leave me alone" or "stop it", and then tell me they've been bothering her, without mentioning what she did beforehand.
For example, yesterday she was in the pool with her siblings and asked me for an ice cream. I said she would need to get out of the pool first because I didn't want food dropped in the water, and if I allowed her to eat in the pool, I'd have to let everyone else do the same.
She replied, "For f's sake, why?" When I explained, she told me to "f off". I ignored the comment, but she then started complaining about me to her older siblings. They listened for a short while before telling her she'd made her point and to stop talking about it and just enjoy being in the pool.
Later, while they were all playing, one of her older siblings accidentally brushed past her. She immediately shouted, "Don't f*ing touch me." I don't know whether anything else happened after that.
She then went to her room and stayed there for the rest of the evening.
This morning it was just the two of us at home. I simply said good morning, asked how long she'd been awake and what she'd been doing. I then asked her to take her washing-up upstairs. She replied "No" in a very hostile tone. When I said it needed taking up, she told me to "f* off".
I've taken her phone away because I'd had enough of the way she's been speaking to me and everyone else. I've told her she can have it back once she can speak to people without being rude or disrespectful.
The difficulty now is that she's barely leaving her room, so I can't really judge whether her attitude has improved because there is very little interaction.
For context, the younger siblings are 10 and 11, and the older siblings are 19 and 28.
