We have a very large fenced in backyard that the girls love to play in. It's a two tiered yard with a retaining wall, though, so we've always been outside when the girls were to keep an eye on them (don't want them to fall the two feet and get hurt!). We also don't have a view of the yard from anywhere but the kitchen window since our living rooms are both on the front half of the house. So, at what age would you be comfortable letting the kids just go in and out and play out there unsupervised? The gates to the fence are all bungee corded closed (and I know they're secure since Paul pulls them so tight that *I* have a hard time removing them! It's supposed to be beautiful today and I thought some fresh air might help the girls feel a little better but I have cleaning to do in preparation for Christmas and company and can't sit out there all day. I feel a little unsure about letting the girls go out without me but I'm not sure if I should relax.
