Thanks for the reply. I would have to buy 15 awards if we re-award them, so that is a good point about the cost of them. I also am having issues with whether they were really earned, particularly for the ones that got them last year. I know some, for instance, have not earned the Webelos badge that is needed.
It's my understanding that the Cub Scout World Conservation Award can only be earned once. Also, we have been told that the scouts can only earn two belt loops (one as a cub and one as a Webelo). That has also been an issue as kids were expecting to get them again from camp.
