I agree about the rough-housing, I just have a hard time with the grey area type things... Like chasing one another. Just trying to find the balance between letting them run wild, and constantly telling them "don't do that."

Has anyone tried a wait-and-see approach with the arguing? I went to a conference recently and one of the speakers had theorized that children miss out on learning to problem solve within their interactions when parents/caregivers jump in to solve it for them. Made me stop me think about how I "let" them play with one another. Just thought I'd see if anyone else takes that approach, or if I'm crazy to even consider it!
