I have a leash for my son, but I rarely use it. I got it when he was a year old and just learned to walk. (He's 18 months now.) He's a darter - there one minute, gone the next, and while he's getting better at holding my hand, I don't always trust him not to dash out in front of traffic. The reason I don't use the leash more is because I've found that we're rarely in situations when the leash is more useful than the stroller. The leash isn't useful when we're at the park, because he's too busy climbing the slide and playing in the sandbox and swinging on the swings to race off. The leash isn't useful at the mall, because he'd rather push his stroller than walk around anyway. Any other time he's out with me, he's either in a cart, or in a place where he CAN play, without having me hover. Really, the only time the leash is useful is in a museum - and even then, I'm not overly fond of it. Don't get me wrong - I LOVE the idea of leashing my toddler. It's not cruel; it's keeping him safe. (He hates me brushing his hair, too, but no one's calling me cruel for insisting on it.) I just haven't figured out how to use one successfully. Maybe when he's older and really doesn't want to sit in the stroller anymore. For now, it mostly sits in the car, forgotten.
