First it would depend on the age of the kids to start out. Second if they are still in school they have to be doing good in school. It must not affect anything else in their life and I would want to have a talk with them. I would want to figure everything out before I started giving them the old secrets of growing. But once I found it was ok and give them all the facts, I would see it as being ok. But then again it does have to do with how mature the child is and how old they are. But overall I would be ok with it.
