My boys (twins) are famous climbers as well. They started climbing out of their cribs at 14 months and would get out of their room and walk the halls at night. I finally had to lock their door and let them cry if they got out of bed. We finally bought them twin beds with the side rails from one step ahead at 18 months and put them on the floor so if they get out of bed they can easily climb back in. We just didn't feel like buying two toddler beds now and two years later two twin beds. The boys got used to sleeping in their beds and have no problem with it. The room is child proof and we have no worries. Although sometimes we have to lay on the floor to keep them in their beds at nap time. To get them used to sleeping in the beds initially we had to just lock the door and ignore their crying until they fell asleep, usually on the floor, and we would just go in later and pick them up and put them in their beds. I think it took them a little over a week to get used to it and then it was fine after that. Good luck! Hope that helps!
