B.D.
As soon as my daughter could stand up, she would rattle the bars of her crib and wail. Then she started climbing. We took the Montessori method, since Montessori considered cribs cages that are only good for keeping children away from dangerous objects. And, if you've got a climber, they're even more dangerous. We got her a futon (full-sized) close to the floor, baby-proofed her room, and put a baby gate up in her doorway. She slept soundly most of the time. Sometimes she got up and played but then went right back to bed. It was the first solid sleeping we had in months! She's 13 months now, and I will never buy another crib again.
