Last year I started packing my kid in an old pack someone gave me. It didn't take long to figure out that if I wanted to pack her someplace other than through a grocery store I needed something better. I did a lot of looking around and after looking at packs, reading reviews and setting my own requirements I picked out a great pack. Its the Deuter Kid Comfort 2. It is very comfortable, the shoulder strap height is adjustable for different torso lengths, it has a great padded waist belt, is set up for a hydration bladder and the kid seat is more like a flat bottomed chair than a saddle. I have put a few miles on with this pack loaded, with my daughter, hydration and gear in the decent sized cargo pockets, and I have to admit it is one of the most comfortable packs I have used. Its rated to hold about a 50 pound kid and I think the wearer would breakdown before the pack ever would. They make 3 versions of the pack the difference is the amount of storage. If you are looking for a good way to get in shape for the season and have a kid its a great way to go. My daughter likes playing in the pack even when it's just sitting on the floor. I need to figure out a way to attach a scabbard to it and it would be perfect.
