Our kids have been entrusted to us. They are watching us do everything and will base the way they speak, respond, react, love, argue, etc. on how we do it. That is a fact. Eventually they will grow up and have to become self aware just like we should be, but right now they are not mature enough or grown enough to be self aware, so we as parents are IT for their learning. Us taking ownership and responsibility over our stuff will go SO FAR in training our kids to do the same.
Remember, our kids don’t look at themselves as kids. In their mind they are whole people and feel that their thoughts, feelings, and emotions are just as important as ours, so that is even more of an indication that teaching boundaries from the beginning is essential to raising healthy humans that will truly change the world.
