C.D.
We used a crib tent with both of my boys. My oldest moved out of his crib at 2.5 years old and the crib tent kept him in his crib the whole time. He climbed out at 9 months, so that is when we bought it. It was great. My younger one just recently figured out how to open it, but until then it was wonderful. He figured it out at about 2.5 years old. The crib tents are nice because you know they are safe in their crib and won't hurt themselves getting out. I think it is a must for any child in a crib.
