It's completely academic where the mother/guardian of the child was sitting at the time he was misbehaving. The salient point is that she was not engaged with what he was doing or how his behaviour was impacting on others. Had she been watching him, she'd have had the opportunity to intervene before someone else had to. And the "circumstances" of the mother and child are not the responsibility of the OP or anyone else for that matter; they are entirely the responsibility of the mother/guardian. OP only had responsibility of the safety and wellbeing for the GC that she was looking after that day, and if that involved checking another child's bad behaviour; so be it.

. No, sorry, that's absurd to expect you to do that. I think in fact you were quite restrained - I would have reacted much quicker and remonstrated with the boy and his carer very forcefully at the first sign of violence. Without people like you stepping in to teach him how to behave (his carer doesn't appear to think this is important), he will undoubtedly grow up to be a bully.
