Our son's last troop gave out parents pins (mother's pins). This one doesn't, I thought it was because they weren't available, or no longer used. But I was just at the scout shop, and someone was buying them for their COH.
I think they are a nice idea, they involve the parents in the rank advancement, and make it a bigger deal for everyone, especially younger scouts.
If your troop does it, would you consider stopping? If your troop doesn't, was there a discussion, and what were some of the reasons to not do it?
