Most the most part, kids can be pretty darn adorable. Especially when they try to act like adults.

Check out the video below of little Jessica who is meeting her baby brother for the first time. As she marvels at how tiny his hands and feet are, the baby starts to do what babies do from time to time and that's cry. After an initial expression of "what in the world is happening here," Jessica goes into full blown mom-mode and tries to calm her little brother down. Who knew maternal instincts kicked in at such a young age?
