flatbusher:
Just read the title. It says ‘raising’ children. So simply assertion at what age you would consider a child to be being ‘raised’, and assume we are talking about that.
As for your next two issues, they have both been dealt with earlier in the thread.
(I have chosen to disregard your query about rabbonim, as you are generalizing, thereby conveniently ignoring the real issue, which, as mentioned above, is children, and therefore entirely practical as regards their usage)
