We recently moved into a terraced house with very steep carpeted stairs, and in the last week DH, DD (nearly 3) and I have slipped down them at least once. (I have an impressive collection of bruises now!) There is a bannister, but all that's done is wrench my shoulder as the rest of me skids downwards.
Are there any products I can buy to stick on carpet that might make them less lethal and won't leave marks (rented house)?
