C.K.
I had this same question almost a year ago when my son climbed out of his crib. He was also OK, just really freaked about it. One mom wrote back and said that her child scared himself so much that he didn't try it again for a long time so maybe be patient. I took that advice and almost a whole year later and my son still has not tried to climb out. He is a climber everywhere else but won't try and climb out of his crib. He is two and a half and I have to say that it's really great knowing when I put him to bed that he will stay there. Good luck.
