It's been a few years since i did a klettersteig in Switzerland and they were all pretty challenging. I did see a father take his daughter on the Allmenalp and i guess she as about 12, and not enjoying it at all. As an alternative, there are adventure parks that will get the kids (and you) off the ground using suspended rope walkways, ladders, ziplines, etc. I think there is one near the Gletscherschlucht at Grindelwald.
As far as klettersteigs go, your best bet would be to enquire at the Alpine Center in Grindelwald, or the tourist centers in whichever town you are in.
Sorry i can't be more specific,
