LOL! I thought I was the only one who uses these!! Man oh man! The stares I get and the comments I hear from the older kids playing on the school grounds (OMG! who would put their kid on a leash!? I never would! - oh yeah! You wait until you have little kids miss priss and your 2yo is running into the road....sorry...appa rently I'm a little sensitive with this topic. LOL!)
I actually think I'm probably quite a sight to see as I push a double stroller, the school girl walking ahead of us, and then have the 2 3yob's on either side of me attached to my wrists with these 'leashes'. 1 is a runner and the other is new and I haven't quite figured him out yet.
The one I use is amazing! I got it from Toys R Us and it came with a bear that the child would wear in the front. You could use this with the backpack thing or just as a wrist strap. I use it as a wrist strap bc the boy would always walk angled leaning forward so a basically had to hold him up (not fun so I pulled that idea). The strap that came with it is awesome because it isn't elastic like the others I have found and keeps this boy with me so he can't have any give on the rope. It's starting to fray but it does the trick The other strap I use is ok http://www.toysrus.com/buy/outdoor-p...26103-13115899 but it has give because it's elastic material so depending on the child it could become a game (hence why I don't use it on the other boy bc he turned it into a lets see how long this sucker can stretch and if the velcro let go that would REALLY hurt flying back onto my hand). This is the only one I can find anywhere though and I didn't want to buy all these backpack things just for the strap. Hope that helps
