Even when, there are adequate playground adult supervisors watching the kids, accidents can happen.
And even if, ALL kids, are given school wide "instruction" on safety and proper use of school playground equipment.
Accidents can still happen.
Because of things like this... nationwide, some schools now, do not even allow kids to play tag or runaround... at recess. Why? Because, kids get hurt even if it is during typical play.
But parents don't like when/if their kid gets bumped or falls down during recess while playing due to other kids.
But then, parents also don't like, when recess activities, are restricted, for the kids.
So it is a very hard fence... to straddle. For the schools and for the supervisors who are responsible for supervising... so many kids.
Accidents can still happen.
And it is impossible to prevent.
Kids, EVEN if they know the rules full well, and even if there are playground Supervisors out there, do things they are not supposed to.
I work at a school. It is very hard, to control all kids, even with many adult eyes supervising. Even after school, kids are doing things they are not supposed to. Climbing the fence etc. throwing pebbles at other kids, etc. things happen in a SPLIT second.
The school your son attends, seems to be very candid about what happened and they are now restricting play time of the kids. And now, this has to be a school wide thing... your son's school restricting recess/play activities of all kids.
And thus, they would need to inform the school's students/parents. I would assume.
Also, the AFTER CARE person or organization, should be doing something about, properly training their supervisors. Many times, the school's after care program, is run by, a non-school organization. NOT the school, itself. But it is held on school property.
So what is the situation at your son's school per after school care?
Is the after care program, the SCHOOL"s program, or is it a non-school organization that does the program on school grounds? If is another entity that provides after care at, the school... then it is that organization... that is responsible, for its employees and rules.
Also, what did your child say about what happened?
How did it happen?
Even if there were adults eyes supervising, it still may have happened.
Especially if another kid was careless and/or pushed your kid off, and/or all the kids there were not following rules, even if they knew the rules.
As you said, the kids themselves admitted... that "there were more students out there on the playground then there should have been...."
And they, knew it. But they still did it.
I work at a school. EVERYDAY, on the playground, despite KNOWING the rules full well, the students... bunch up on the jungle gym and play tag there and bunch up in groups at the top of the slide. EVEN IF, there are... adult Supervisors there.... who are telling them to get off, it and stop it.
And the kids, don't listen, they do NOT listen.... even if you are blue in the face. But we can't touch or handle the kids to get them off it, because then the kids will say that we "assaulted" them or were "mean" to them and they go home and complain to their parents. Then the parents get mad... that we don't let their child play.... at recess or whatever.
Accidents on the playground or at recess or after school happens.
Even if there are rules and adult school staff, everywhere on campus.
And even if kids know the rules, they do not always listen or do as told.
And/or other kids are rougher... and more boisterous, and then a kid on the sidelines may get hurt. MANY MANY scenarios, of this and how a kid gets hurt.
You work at that school so you know everyone there.
The school, is ALREADY doing something about it: they are restricting, play activity at school. Because of the accident your son had per that incident.
What else would you want? Are you going to sue, them?
All the kids, and the school are deeply affected by your son's accident.
And their playground play/recess/after-school play activities, are now, changed.
But they should ALSO, make sure the After School Organization at their school... has all personnel trained, and are abreast of that school's rules and by the Principal and per any legality etc.
I imagine, the other kids and parents will now wonder, why their playground/recess time activities, are now changed. From free play/unstructured time, to now, structured, play.
