We don't have stairs in our apartment (thank all that is good for that), but when we were at my mothers last week, DD took it upon herself to do nothing but try to climb the stairs. One of us was always behind her when we allowed her to climb up, but it's terrifying and I'm so glad I don't have to fight that battle on a daily basis!
I am excited that we found a kit that straps around the lower banisters so we don't have to drill into them. We'll have to drill into the drywall at the top of the stairs, but I'm not as concerned about the top of the stairs yet. We're always downstairs
