So you've never even tried it? Like I said it belies a desperate lack of experience.
Something like 150,000 kids have done NICAS, I think if there was a problem with the 7YOs it would have raised itself by now.
The Foundry in Sheffield is advertising for Lead Climbing Team members ATM and the age range is 7-13, no chest harnesses there.
My local wall puts 5 YOs in an Alpine waist harness and their NICAS too, I've seen literally thousands of their sessions and they don't need to resort to chest harnesses.
Have you ever seen a 7YO kids sessions at a wall?
> A climbing wall is a very controlled place - perhaps indoors, just top roping, with zero danger of inversion, I'd risk a sit harness if that's all there was. But outdoors, no. Either place, what's to be gained that outweighs the increased safety margin of a full body harness?
I'm not clear why you think an outdoor face is much riskier, or why you'd think there is zero chance of inversion on an indoor wall, but it sounds like you don't have much useful experience of kids in indoor/outdoor climbing environments.
There's nothing wrong with not knowing of course but best to limit the advice to areas you know about.
