My daughter is 2 1/2 and 25-30lbs. When she was a little baby I used a moby wrap and an ergo carrier, and I have two framed back packs that I bought at garage sales that I have used since then. We do a lot of local hiking, and for the most part those two framed carriers have worked fine with no major discomforts.
I've decided to kick up the hiking a few notches this year though. I'm planning camping trips for this summer where there will be a lot of long distance wilderness hiking like I did before she was born. I know the packs we use now are going to leave me in pain if I try to cheap-out and use them in place of a higher quality pack. I can't really afford to just keep buying and trying though. I would like to get your advice here so I can hopefully just make the investment once.
What packs should I consider to carry a 30-50lb child, sometimes in rough terrain, for many miles at a time? It would be a bonus if the pack somehow integrated additional areas to carry tent/sleeping bag/hydration systems/emergency supplies/etc., or at least was designed in a way so that additional items being carried wasn't too problematic. (I'm getting creative this year however and buying a pack for the dog so that she can carry some of the load too... lol.)
Any advice would be appreciated.
