How can I punish Delos (year and a half)? Spankings aren't working. He won't sit long enough for time outs and that will just piss me off more to fight him than to just punish him. I don't have a place to put him in to keep him contained for a couple minutes. He's getting so bad with temper tantrums. I just ignore the tantrums normally but it's not getting to the point where Jace can get no peace because of it. HELP PLEASE!
