It's a well established fact that Jefferson has a very active big brother.
For the most part, he does a pretty good job of keeping up with him and trying to act like a three year old himself.
Jefferson bypassed baby toys and baby foods and went straight for the matchbox cars and chicken nuggets.
So it's no wonder that after all the chasing after, fighting over, jumping on, and wrestling with big brother...
...the little brother can't stay awake through lunch.
