If I really want to be extra safe, I need 4 sets of these cos I have stairs that are going both upstairs and downstairs.
We have also decided to add clear polycarbonate sheets to my staircase railings, so that my "hero" wont have any opportunity to put his foot on those railings and try to be super or spideyman!
He is in the "jumping" phase now. Jump from bed to the floor, jump from one chair to another, jump from first staircase to the next and all the way down to the last staircase. Jump even when walking. Meaning he does not walk step by step. He jumps step by step. *pening*
