Katinka randomly will start running laps (like REALLY fast) around our apartment at odd times. It is hilarious. Sometimes Kevin & I provoke it by scratching her belly really fast and making her hyper. It is so funny and hopefully you'd had the pleasure of seeing her do it! Here is a video that a girl who babysat Katinka took on her phone. [So it is not me laughing in the video, lol] Check it out! IT IS SO GREAT!
