This is a common breakfast scene. Felix is getting some cereal while Max looks on. In this case, Max is in his kidcart; he's often in his bouncy seat. The kidcart has a tray that allows him to play with toys and has other benefits. I have my reservations about the kidcart, but that's a discussion for another day. If nothing else, the kidcart lets Max have a better view of that which he is most fascinated by: his older brother.
