Ticklish?

Brayden is growing and changing so quickly. He is starting to smile (haven't caught that on camera yet), finding his voice, and becoming much more alert. He likes to be naked and anytime that he is fussy I can lay him down, take his clothes off and rub his feet. He is also getting ticklish even though he doesn't know how to react to it yet. In the video if I tickle under his armpits he will tense up his arms and legs and raise them straight into the air. It is kind of hard to tell but it is pretty funny.
