Ben's almost four and so far he's NEVER attempted to climb out of his crib. Up until now I was waiting to hear a thump! of him falling out of it or see him come running out of his room with glee before I transformed his crib into a bog boy bed. Weellllp.. last night on a whim, I said screw it! That side's comin' off. When I yelled downstairs that there was a surprise waiting for him, he scurried upstairs and quickly declared that I broke his bed! Actually, it sounded more like this: "MAAAMaaaaaAA?! You broke my bed." Why, yes, yes I did. I definitely thought I'd have a night creeper roaming into our room last night, but he stayed put! He loves his new bed and changes his sheets go so much easier. So far, this is a total win-win!
