When I take DC to school, we are usually in the playground 10 minutes before the bell goes so as to get a parking space. We are usually the first there, and the playground is unsupervised until the bell goes. Another parent in DC's class arrives the same time as us, bringing with them another child, which obviously they have assumed duty of care for. They then also join the line (school discourages chasing around before lessons.) As soon as we appear, the parent shoots off, and doesn't even ask me if I mind looking out for their child and the one they are supposed to bee looking after. This morning, yet another parent left his DC, but he doesn't do it every day and I didn't mind because he asked! I was the only parent there. All the children (my own DC included) got overexcited while in the line and there was some horseplay. I could see that there was potential for someone to get hurt and so made a judgement call to speak to the children about this. But I don't like being put in this position. I am there to make sure my own DC goes into school safely, not to oversee other people's DCs.
I foresee being placed in this position most days, especially as most parents arrive with their DCs just as the bell goes.
We could arrive later, but then parking would be harder with the potential to actually arrive late.
Should I tell school about this? I don't relish a confrontation with the parent.
