We have a 18 foot round above ground pool in our backyard. We currently have a standard ladder that goes on the outside and inside of the pool. It can be difficult to manage. I want to build a deck with stairs and a lock. I think it would be safer. My husband is nervous to build a deck because he fears our one year old will get up on it and climb in. To those of you who have been in the same boat before, what would you choose?
