Rock climbing is hard as hell.  It takes a ton of upper body strength, concentration, and forethought, all of which are not strong suits for most 2 year olds.  This baby is an exception though, check out this diaper wearing rock climber.

Most babies can't do anything, other than poop and need stuff.  This kid is awesome though and probably at least half monkey.  I'm impressed when babies learn how to not crap themselves, let alone climb a rock wall.  Some people are going to say the baby is in danger, but that baby ain't scared.
