Dunno how old or experienced your kids are, but we did some 'bungles walking and climbing with the kids last year. Our party had grommets beween about ages ten and five. If the grown ups are going to do Vertigo, there is some stuff for kids just beforehand.
Walk in off the main walking track as for Vertigo. After the first scamble / steep section of track up, there's a big block my kids called the minifig backpack man, as that's how he looks from the main walking track near Balor. It's before any of the actual climb/scramble stuff to get to the true start of Vertigo so heaps safer. There is a simple face with craks and slots and stuff that's great for kids. Easily protectable with gear for the leader. There's a few slings around on top for the last person up to rap off. We top belayed but you could set up a toprope. In the pic below it's the block below the brighest spolt of sunshine, directly centre at base of crag - but not the very lowest cliffline / rock outcrop in the pic. Not in any guide but obviously climbed on a bit, and with fixed tata at the top. Have fun, great area.
