So my two year olds cousins (who we live with) are mostly badly behaved. Their parents barely discipline them so they think it's ok (they are 3 and 4). The problem is, my son always wants to do what they are doing. If they are screaming up and down the hallway, or jumping on the couches, he wants to do it too. Is there a way to stop him without looking like the "mean one?". I dont condone a lot of the behaviours they allow their kids to do. If anybody has some tips that would be great.
