Sleep Walking?

So this past weekend we had our first confirmed sleep walking incident from Carter.  Steph and I were watching a movie on Saturday night about 11 when Carter came walking up the stairs.  Once he got upstairs, he laid on the couch for about ten seconds, then he got up and walked into our room.  Mind you the whole time he is doing this he is holding his nether regions.  I get out of bed and lead him to the bathroom where he attempts to pee on the sink.  After completing his business he climbs into our bed only to have Steph attempt to wake him up and walk him back downstairs.  This is shortlived as he gets to the top of the stairs and laid his head down and goes back to sleep.  We get him to the couch and he slept the night through, in the morning he had no idea what had happened.  Carter had a sleep over on Friday night with his friends Jack and Cole, of course they stayed up late playing video games and watching movies.  Of course on Saturday morning they were up bright and early to eat their pancakes and bacon.  Carter enjoyed his week off for spring break, but I don't think he was ready to go back to school.  He spent a lot of time over break playing with his friends outside and the weather cooperated.  Hadley has her 6-month check up this week, so I will update her height and weight later this week.  She has been eating about two foods a day and is doing really well, even getting upset at mom and dad for not getting the food into her mouth fast enough.  She is still sleeping through the night and allows her dad to get his work done during the day.
