Hi, sorry for my late reply, alot going on and haven't been in steem-land the past few days.
Number 1 pro is that they are both very clear, awake, aware, self-motivated, introspective and creative people.
Un-schooling also allowed us the freedom to travel with them.... which we managed on a shoe-string, in fact, looking back I have no idea how we did it! Lots of camping and hostels which kept them connected to earth and meeting interesting people along the way!
Can't think of any real cons....perhaps a con is that they didn't have the same solid group of friends throughout their childhood....but instead they have amazing friends in many places, so it is not really a con.
Peace ~*~
