DS is proving to be quite the explorer at nightime and coupled with starting to sit up and topple over again he is bumping his head and all other parts of his body on the side of his cot with more and more regularity.

He is looking a bit bruised and battered and is waking himself up with his antics. Any safety guidelines I can find say 12 months is safe, so should I put up with another 5 months of bumps or has anyone introduced one sooner?

Or perhaps is there an alternative option?
