When I was a wee bairn, we had steep stairs but I was fine with them. I would bump down them on me bum, everything was cool. Then my grandfather took one look at them and sterlny INSISTED that my parents install a baby gate at the top of them so that I do not fall down. They are faaaar too dangerous you see.
So InquisitiveLateralThinkingTommy works on this problem, builds up a pile of stuff - a chair with books on I think - to get around said obstacle.
The result was a hospital visit and lots of accusitions that my parents abused me.
I say no to stair safety gates
