In reply to wolfcraig:
> So, your point is that children should not be allowed at a climbing wall or bouldering wall?
Nope. My point is that parents must be in proper control of children in climbing/bouldering walls at all times, and must understand their responsibilities in doing so. And for everyone's safety, need to be warned then thrown out if they do not properly carry out those responsibilities.
Though I do take the view that an under 5 (ish) is in most cases going to get more out of a visit to a play park or even a very slabby crag on top-rope than an artificial climbing wall, simply because of the way the wall is set up with the gaps between holds. And this is from experience - my nephew, when he was very young, got far more out of playing on a really easy crag than anything involving spaced-out bolt-on holds - also I'm an instructor at a Scout wall, and even some younger Beavers (age 6-8) have trouble getting much more than a metre or so off the ground - and that's on a slabby wall where rainbowing gives a grade of about F2-2+.
As regards older children, no issues at all with them, as they tend to be old enough to realise that running around the bouldering area without looking up is not safe, know when to stay still when told to do so, and are also less vulnerable to being killed if a rugby player falls off the wall above them and lands on them. And also might understand what is meant by someone shouting for them to get out of the way if they do inadvertently end up in danger.
With regard to roads, I would take a broadly similar view - children should not be out on their own until they are old enough to know how to cross a road safely unless in something like a "home zone" with cars only at walking pace and absolute pedestrian priority, or indeed on the MK Redway system where there is no need[1] to cross any roads. (I like this concept, FWIW, but it isn't going to happen if your house is on the A1).
[1] I do however get fed up seeing young kids ignore a bridge/underpass and run across a 70mph dual carriageway, then the parents complain when they get hit by a car, when they should in fact be ensuring that the kid *knows* not to do that and is responsible enough. Yes, you can learn to cross such a road safely, but at those speeds kids just don't have the judgement it takes - really at that age "if you can see a car it's not safe to cross" - and as these roads are quite busy that won't be often!
There will be elements of judgement in this, of course.
