I was feeling really frustrated and am sure was sounding like a broken record. "share" "please don't take that toy". So, I tried an experiment yesterday. In my head I was thinking, they know this is wrong, I'm not teaching them something new...just nagging (reinforcing) the point over and over. So, I just sat back and ignored those situations between my 2 year olds. Obviously, there were exceptions (any sort of physical violence, bullying etc.). I was amazed. I honestly assumed the bully would remain the bully and think "cool, I can just take what I want".
At first, they would just stop and look at me (hmm how come I'm not getting in trouble). As the day progressed those behaviours were more and more infrequent and I was a lot less stressed. No idea if this is the right thing to do, or if it would work long term, but it was a great day!
