Vigorous head shaking

I’m still doing my head shaking thing. Now it is not only when I hear music or am happy. Sometimes I do it when I’m just feeling silly. Other times I do it in response to a question. It looks like I hit my rebellious stage very early. It makes Mommy and Daddy laugh when I shake my head, but sometimes I think they are a little worried about my brain sloshing about in my head when I shake too vigorously. I don’t know why they worry. I’m fine. Now can someone please stop this room from spinning?
