DS1 is 26mths old and today he has tried to stand on Ds2 head, tried to hit him with a train, tried to headbutt him and managed to bite him on the face while pretending he was going to kiss him.
Don't know what best course of action is. Have been trying to explain it will hurt him and that its not nice. This clearly isn't working as if anything he is getting worse.
Anyone been through this? How did you deal with it?
