Sleepwalker

Jacob is a sleepwalker. Twice in the last 2 weeks, he has gotten up and done relatively the same thing. The first time he came downstairs into our bathroom and stood up by the toilet and cried. The second time he went into the bathroom upstairs, sat down on the toilet and cried. What in the world is this all about? I am thankful that I was up for the second one, but the first time Greg had to wake me out of a deep sleep. I hope this doesn't get any worse than it is.
