Amber has discovered the joys of perching on the top of the sofa back in order to watch the world go by. Trouble is, there's a good half metre between the sofa and the wall. The sofa has a metal frame with a mattress thing on it that is sunken by about an inch to begin with, and obviously sinks more with weight. If she can get up and down herself, will she be ok? Should I discourage her from doing this? Or should I rearrange the room to make it safer? Trouble is, the back of the sofa is used as a bookcase of sorts for all the collectable books I can't fit on the bookcase!
