I take our kids out climbing (aged 11,9 & 4). 
The trick is to setup 2 ropes, one on easy pitch and another on something that will challenge yourself. I wouldn't have any of them belay for me yet, but the oldest one isnt too far off. Perhaps with a grigri, and a good belay anchor so they don't get hoisted up 10 metres. 
 
My other half makes a good belay slave, she enjoys the walk out and has a go at the odd climb herself.  
 
Kids are good for loading up with ropes and biners, 6pack of beers etc...they feel really important carrying all that climbing gear....especially those steel biners :) |
