Will my 16 year old be considered a "Child" still for any of the rail passes?

I'm trying to figure out what to expect budget-wise for travel into this region. I'm travelling alone with my 16 year old daughter and
I've read in a few places that the children's rate for either the Jungfrau travel pass or the Berner Oberland Regional pass may or may not include 16 years. I've read it both way in a few places. It would be so lovely to save a few dollars but I'm also not going to lie about her age. Anyone have any experience traveling with a 16 year old to the region?
