My two boys were fighting today.  D, who is 7, loves to boss around N, who is 4.  He yells and lectures him.  So N has his fill and traps D by putting his arms around him and holding onto the gate that is on the other side of D.  D gets mad and pushes him off, throwing N against the cabinet.  N falls down crying, gets up and goes to attack D.  That's when my mom stepped in.  I was pretty clueless as to what to do.  I thought my mom handled it well.  What do you do when your kids fight?  Or how do you keep them from fighting?
