My son is almost four months now, so he's learning how to grasp objects and bring them to his mouth to chew/suck on. He also just LOVES to suck on his fist and arm. He'll do it for hours and hours. He's even given himself hickies on his arm, hehe.
So today he was chillin' on my lap when he suddenly sticks his hand straight out in front of him. He rotates it for a little while, just staring at it like he has NO idea what it is, and then he makes this hilarious face like it's the most amazing thing to
ever cross his eyes, right before he shoves it in his mouth as fast as he can. Then then proceeded to attempt to swallow half his arm.
It was too funny!
