the science of sleep(lessness)

Here is the scene from this morning - me, my dad, two cats and a baby.  I do not look very glamorous, even compared to my normal standard.  I'm afraid it's the best I can do what with existing on about three hours' sleep a night.  Yes, we officially have a nocturnal baby and it's driving me mental.  Last night she was up until 5.30am (and I mean not sleeping at all and screaming whenever she wasn't being fed) and then when I finally did get her down she slept for a measly one hour before waking up for more food.  So by 7.30 this morning I had had one hour's sleep.  One hour.  For a while she could only keep this up for a couple of nights before being too tired to stay awake the next night (oh, the blissful memory of nights where I was getting two-hour stretches of snooze between feeds) but now she seems able to do this every... single... night.  Ugh.  Our attempt at getting her into a day/night routine has not been working but I am upping the ante this week and the two of us (Dulcie and I) will be plunged into a post-bath world of darkness and silence from 8pm every night.  Meanwhile we are trying to keep her awake a bit more during the day but I swear this baby can sleep through anything.  When it suits her.
