Conflicting emotions

My wife sent me these photos of my three-year old daughter and my three-week old son, and at first, my heart was warmed by the affection that they obviously have for one another.

Then I looked closely at their facial expressions and realized that in each photo, the emotions of my daughter and my son appear to differ considerably. 

In each image, one child is quite happy while the other is decidedly less than comfortable.

Poor Charlie.
