I would think as long as the pack wasn't over loaded, it may be okay to just to get them used to having it on their backs. I saw that episode too, but I can't remember what he put in the pack. I've thought about putting the pack we have on our six month old, but with nothing in it so there is not weight on his back. I was just thinking that it would be nice if he got used to the feeling - even if the pack is empty. 6 months does seem way too young to put anything of substance in the pack.
