when you can no longer easily restrain them?
We've generally tried to avoid "punishments" in favour of "natural consequences". DD is pretty good TBF, so we haven't had to use either a lot.
Occasionally (when disregulated or very pissed off at being told no!) she will be violent - hitting, kicking etc. When she was smaller we'd react to this by putting her on the other side of the kitchen baby gate and saying that we had to stay away to keep ourselves safe. These days of course she can just climb over, so we've tried sending her to her room, but she won't always go, and if I try to pick her up and carry her there (as I would have done when she was younger) it ends up in a physical struggle, which feels horrible (and I'm also worried about her wriggling out of my grip on the stairs 😱).
So what do we do? Is a screen time ban punishment the only option??
