Momof2, my daughter was 11&1/2 and I thought she was WAY too young for tampons. Unfortunately she missed a couple of events and had a Girl Scout trip coming up to Hershey Park. We counted out and sure enough it would fall then. I finally relented and informed her as best I could, (there is a great diagram in the box) and said if you can figure this out and are comfortable with this you can do it. She was fine and it has made the summer a lot more fun for her. We have neighbors with a pool and lhave 3 beaches here in town! Of course it is absolutely your decision, just thought I'd share my experience.
