Annika told me today, "I don't like you anymore, Mom."
This barb had surprisingly little impact on me, and thinking quickly (not a strong suit), I responded: "it's not nice to say mean things like that to Mommy. If you say it again, you are going to time-out." End of discussion. I still marvel at the fact that time-out is such an effective punishment, at least for now.
Another good punishment we've discovered is "denying the goodies". Annika pitched a fit when I said that Dogarita couldn't go outside, so Dagny and I went to the mailbox to get the mail without Annika (who remained in the kitchen, screaming). You would have thought I cut off the kid's leg. She was much nicer after all of those nasty screams were released, though.
