Either one or both of my 2 yr old mindees have peeled a great swathe of wallpaper off my living room wall, I was in the kitchen making lunch. thought they'd gone quiet so went and checked to see what they were doing, came in to be confronted with the missing wallpaper. HelpI can't hide it as it's by the door and it's the first thing rthat you see when you walk in the room. It is also irirepearable (sp)as the piece they have removed is screwed in to lots of little balls!! Help please!!
