If you ask her pediatrician, Vivian is 31 inches tall and weighs 21 lbs.
If you ask Vivian (Wie gross ist Vivian?), the answer is pretty self-explanatory (Sooo gross!).
If you look at the pants her Omi sent her, she still has a bit of growing to do.
Or, you just put a big sweater over it.
And add a few more layers to dress her for winter. :)
