Thank you. Yes, good point. The way my little buddy works, boundaries are frequently tested anyways, and sometimes they fall when we feel he's ready - I think it's kind of a natural, almost automatic process. That being said, rationally balancing risks vs. freedoms is the most intense parenting task IMO.
The other important part - remeber to losen the boundaries as they continue growing up, so when they are 18-ish there is no difference between boundaries on and off.
