I have had those nights, too! I had to get up and eat a little something last night to go back to sleep.
I think the baby might be getting ready to have a growth spurt. I have been doing pretty well with eating, but yesterday I was craving a cheese danish or cinnamon roll or something of that nature. My mom brought some homemade cinnamon rolls to my work, because she happened to be going to Mennonite bakery out of town yesterday. Mmmm. So bad but so good!
