Never avoid any opportunity for growth! The Lord sends young men on missions, sometimes to dangerous places, and gives them experiences we, as protective parents, would never let them have. He wants us to be IN the world. To live and experience and learn and grow. And hopefully to be shining examples of righteous choices.
Steve and I have struggled with what to limit and what to learn from... They will go out into the world and experience temptations eventually. Start now, yes age 2+, to let them be "tempted" while you are still there to guide and help them recognize the consequences of those "temptations". In this case if he is rude/bossy/mean, he will be unhappy with the consequences and not be able to play happily with those he chooses to bully. Ezra will learn that he has to choose how HE will act, even when others around him are acting differently. What a life lesson! We always told our kids... others have their agency, but we (our family) choose differently and we are happier for those choices.
It is so great when you see your kids recognizing for themselves what they want to do and the reasons they want to do them. (Not just doing things because Mom or Dad is there hovering and threatening.)
GO BRAD!
