Tekla started singing while upstairs in the bathroom. Then she continued as she came down. Then it continued. Daddy got the camera and it continued. Daddy stopped filming and it continued. It only stopped when Mommy started watching what Daddy had filmed.
If you look behind her you will also see the trampoline that we got the girls to help them burn extra energy when Mommy can't take them out. We have been amazed that this little one who had gross motor delays so early on can jump longer than her sisters(maybe not as hight but longer).
