Boo Boos and belly buttons

My poor little boy. He constantly has some sort of "boo boo" on him whether it is from bumping his head on the same spot over and over (i think he might have permanent bruising), bumping his chin and biting his tongue over and over, or falling a scraping his knees. And boy is he messy. Maybe it's a boy thing because when i pick him up from daycare, none of the little girls look like that! And this is just the beginning! Recently Seth fell and scraped up his knees. He barely even whimpered and just got up and kept going. When i ask him about his "boo boo", he points at his knees. Seth has also gotten really good at pointing at his eye, nose, mouth or ear when you ask him to. He has also discovered his and mama's belly buttons and likes to show his off.
Here's Seth showing off one of his boo boos:

And here he his pointing to his belly button:
