We're buying an older house with a beautiful old bannister and a balcony on the landing. But the bannister/balcony is 90cm high and there's a long drop down. I have 3 young DC one of whom is a climber and am worried about it. I have seen guards to stop children going through bannisters but nothing to stop them leaning/falling over. We could take them out and start again but that would be very sad as they are beautiful so i am trying to find a cost effective solution. Any ideas?
