I actually thought I was very free range until I read this thread! Haha. I let my babies play on their own, and I sit at a distance unless the little one is climbing on something where he needs my help or is likely to fall in which case I'd be right beside him. But mostly I'm a sit back and watcher. I'd never take my eyes off my little one though. My eyes are plastered to him most of the time, and then I gaze around occassionally to check on the other 2, but always watching my littlest and ready to get up and run if I'm needed.
