My most recent one with dd2 (she has special needs, but I am well aware that that is by no means a pre-requisite for the kind of thing I am talking about...) was going into her room in the morning to find that she had not only ripped her carpet up (which I had nailed down), eaten some of the underlay, but also pulled some floorboards up
She had strewn the room with some old newspaper which must have come from the murky depths beneath the floor...it was orange, and so old that there were news articles about Dennis Healey and Barbara Castle...she had probably eaten some of that too
So come on, who can beat that? I need to know if your children are as horrid as mine for purely healthy reasons of comparison
