It seems to have become a bit of a habit for me to wake up at 4am! I'm not really sure why, as Elmo is still fast asleep, but there we are! I have experienced a similar thing with all of my pregnancies, and usually the time I wake up during pregnancy is the time the baby wakes up after he/ she (but mostly he) is born.
It's difficult to know what to do. On the one hand I am usually fairly awake and can get things done, BUT if I do that, it means I am shattered for the rest of the day and soon that will mean I am tired at work. If I lay in bed, I am tossing and turning for ages, though I do entertain myself with Twitter, Facebook and Sims!!! Very often I also disturb Lewis, though I try not to!
Anyhow, I got up this morning because in addition to my 4am wake up call, I also seem to be really hungry the last few days and I forgot to put cereal bars in my drawer yesterday. So here I am, awake at silly o'clock and pondering whether or not to have asparagus for first breakfast....The joys of pregnancy!
