climbing monkeys

Brynden is my climber. He climbs out of the walker and he climbs onto the coffee table. He climbs into the man box(an 18 gallon tote) he climbs everywhere. Its becoming a problem when i put him into his crib for a nap (which he did not take) and instead of playing with his blocks which was naughty enough, he decides to climb out of his crib using Boston's dresser and i go into check on him cause he was too quiet and low and behold he was perched on the dresser two hands on the crib and one chubby leg falling off the dresser...... i about died. what if i wouldnt have checked on that naughty monkey??? and what do i do now?
