Every time I turn my back one or both of them is doing something they shouldn't:
Sharing food/toys/saliva
DD in the dog's bed, dog on the sofa
DD emptying the dog's water bowl all over herself
DD has just started sleeping properly for the first time ever so the dog has now decided to wake me up at 5 every morning 
I'm telling you, 2 against 1 is not good and I'm fairly certain this is just the beginning...
