I don't know if this belongs under behavior or under multiples. I really don't think this would be an issue if they weren't so close in age. Anyway. They're climbing everything. Dining chairs we can remove from the room. The couch only has a couple spots where they can fall directly onto the tile, so that's not even the biggest deal, although it's challenging to spot both of them at once. The worst is the twin bed we have in their room. They can climb it and then they get wild and bounce around and inevitable someone falls off. And even worse, someone bangs a head on the wood frame. None of these are life threatening injuries and my tendency is to let kids learn to be careful by falling a bit, but this is a little too much even for me. Especially because every bruise has to be reported. Suggestions? They both know how to get down backwards, but they feed off of each other and get wild and that's when they fall. We've tried asking/making them sit while on the couch or bed but so far that's not sinking in. They're 16m and 18m.
