Using tickets for my 4 yr old ds and 3 yr old dd. I gave a large margin for error. My ds is trying to not argue or yell now and doing well. My dd is not trying. She will argue just to get a ticket away and tell my ds "we get a ticket taken away!" Like "ha-ha". Not sure what to do since she's 3 yrs and 5 months old. I started yesterday so no time has been spent in room separated yet for arguing, but my dd is trying hard to get there today. My son gets upset and tells her to quiet down b/c they only have one ticket left. Do I send her to her room for causing trouble before last ticket goes or wait to send both?
