Our kids both went for some major hikes in our backpack. They usually had a very good nap while I was getting a good workout. One thing that we did that you might helpful is to get a handheld mirror and tie it to a string attached to the back pack. It would just hang off the side but could be used to check out the kid to see what they are doing (ie. napping, hat still on head, etc.). Very handy if you do not have the other parent with you.
