One of the reasons I journal, and one of the reasons I blog is that it helps get the running commentary out of my head when my head just gets too crowded. Basically, it's an alternative to talking to imaginary friends. And when you're currently spending hours a day feeding a newborn, you end up with a lot of thoughts running through your head...of course you also end up with not a lot of energy/hours in the day to write, but we do what we can.
