Mom keeps a watchful eye out

Mom is a great mom - keeping an eye on her entire crew  - between the four of them, they manage to keep the entire Xpen a hopping... (smile)...  When not be-bopping around, Vienna tends to stay almost side-by-side with Paris and I am wondering if she senses there is also something wrong with Paris?

Not that Paris needs protecting, because she is just as apt to take on her middle sisters as she is Berlin!
