I can't believe I did it!

I get the feeling that no one really believes my Mama when she tells them this, so I am here to set the record straight. On Saturday I was playing on my tummy, and I rolled over onto my back all by myself. Apparently I'm not supposed to be able to do this yet, which is probably why no one quite believes my Mama. What can I say? I am Superbaby and I have superhuman powers. Oh, by the way, my new favorite thing is when Mama or Daddy holds me around my chest and I push my legs down onto their laps like I'm standing. It's tiring though so I can only do it for a minute or two, but I love it. I'm also working on learning how to laugh when my Mama tries to grab my tongue, which I stick out constantly.
