Leave Me Alone!

We were trying to get Tyler to bed last night, he kept getting up and refused to stay in bed. So, Mike told him to sit in timeout until he was ready to get in his own bed. After some crying and whining, Tyler quieted down. Mike checked on him after he'd been quiet a minute or two and asked if he was ready to get in bed. Tyler said,"No, Daddy. Leave me alone!" I don't know where he got it from, but I guess it's a step up from "I don't want you!" which is what he usually says. I had been telling Tyler that he shouldn't say that ("I don't want you") because it's mean and hurts our feelings. Maybe he really listened and figured out something else to say instead?
