I'll admit it, I used to make fun of people who put their kid on a "leash." But now that I have a one year old, who thinks he can do anything himself, I am all for "leashing" my kid. I've seen quite a few stuffed animal backpack style harness. Here is my homemade version (please click on the pictures to make text easier to read):
-a stuffed animal
-3 3/4 yard nylon webbing
-2 adjustable strap pieces
-sewing machine, thread, embroidery floss, thimble
I couldn't find packaged adjustable strap things, so I bought a back pack from the dollar store and took the these pieces off.
Take a lighter and burn the edges on all pieces to prevent fraying.
Grab a thimble for these next steps. You are going through a lot of layers so a thimble really helps.
To Finish it off, thread the 23" pieces back through the adjustable strap pieces. Fold the ends over twice and stitch to prevent the straps from slipping all the way out (like you did for the chest straps)
Attach the "leash" to the D-ring and you're good to go.
Questions? Leave me a comment or send me an email.
p.s. I know in the picture there are a lot of extra straps hanging down, but I wanted to leave plenty of growing room. Magoo is 15 months and 22 lbs. This should definitely fit throughout the toddler years. But feel free to shorten the straps if you're child doesn't need the extra room.
