Hello.I wanted to ask about my son who is 10 who wrestles and plays with his siblings who are younger. He has been mildly aggressive being much older. He has mildly choked, smothered with pillows, etc. not to the point of hurting them yet, but they do cry about it. He has been disciplined for this since he scares them. I am afraid it may escalate and he may harm them. What is appropriate discipline for this? I have sent him to his bedroom and given strikes for it.
