Looking for a child carrier to make hiking with the kids a bit more enjoyable. My 4 yr old can go a mile or 2 but my 2 year old zonks out and we've ended up just carrying him. My torso length is 21" and generally a medium sized hip belt works, though most of the pack look pretty adjustable. So what do you have that your own have grown out of? It's for this cheese ball: image.jpg
