Why oh why?

Aaaaaaarrrrrggghhhh – why oh why have I woken up at 4.12am exactly for the last three nights? What is my body/mind trying to tell me? That I should get up at this ridiculous time? Is this some dreadful premonition that this is the time the new baby is going to wake up? I hate waking at that sort of time, it takes me ages to get back to sleep. It always feels like I’ve just fallen asleep then my alarm goes off. I’m going to be Mr Crankypants today.
