dd2 is nearly 4. She's always been rather feisty, but currently we are really, really struggling with her. Any gentle attempt to enforce basic boundaries is met with full on screaming of the "NO I WON'T DO IT! BAAAAAA!" variety, and she won't stop for a loooong time. We're not a very shouty household, and her older sister is pretty calm, so I don;t think this is behviour she's learnt from us. We generally try to stick to natural consequences as much as possible (right now she's screaming because I won't play a board game with her. I told her there's no room, and she needs to tidy a few toys away with me to make room first). This happens many, many times daily, and as a result it seems that she is not very happy for much of the day.
Anyway, my nerves are increasingly shattered by the constant screaming, and I'm worried for my poor neighbours as we're in a semi-detached. She's an angel at preschool
so we don't think it's SN of any kind. Otherwise it's that bad that I would be worried about this. Any top tips?
