To leave your child outside unsupervised? We have a fenced in backyard with a lock on the gate that DS1 can't open. He's got toys and a sandbox out there. He's 3 and a half. Is it safe to lave him out there for a few minutes alone? for example for me to go make lunch or put ds2 down for a nap. I'm not going inside and watching a movie while he's out there, but dh said he doesn't think it's a good idea to leave him unsupervised. I'm just wondering what everyone else does?
