I don't think our crib has a third setting (we have an ikea) and if it does we put it on the lowest anyways. She is learning things so fast I wanted to make sure it was on the lowest setting just in case she wanted to learn to pull up in the crib overnight!
I think it depends how far she can lean over. I had to move mine all the way bc she was leaning forward on the middle setting (which I determined is a pointless ass setting). I'd lower it to be on the safe side and not have to do it again later anyways.
