surprise!

I had quite an interesting thing happen last night. I know I was sleeping, when I felt Tom sliding back into bed. I moved over so he could get in, as it seemed I was close to the edge. But wait... why was he getting in my side of the bed? Maybe I was way over on his side and he felt it would be easier to get in on my side than get me to move over? But that didn't make sense. I began to drift back to sleep, but for some reason, I reached to find Tom. Yep, there he was. And the clock said 12:45 am. But something was behind me. Did one of the kids come home and climb into bed with us? omg You guessed it, and so did I. It was my dad.

me - hey dad
dad - yes?
me - I think you came back to the wrong bed.
dad - what the hell?

He immediately scrambled up on his feet and asked "where the hell am I supposed to go now?" I got up, suddenly hoping that he had his underwear on - which he did- whew, and walked him back to his room.

dad - "Is there anyone else in there?"
me - "no, Dad, just you".
dad - "OK, night"

Yes, it was funny. It's OK to laugh. But now I have to figure this out. All the doors in the hall are shut at night, except the bathroom and our room. I feel like I need to keep ours open so I can hear him get up, check stuff, etc. Obviously, I didn't hear him get up last night. There goes that theory. There is a night light in the hall, and one in the bathroom. He gets up every night 1, 2, 3 times. Why did this happen tonight? There goes my theory about how routines help. (they really do help, but not tonight! ) There goes my thought that the lighting I have in the hall/bathroom is enough. Today, I was thinking about getting a motion sensor night light to put in his room. I thought that when he got up, the light would go on and still be on when he got back. I looked online, and the longest any of them stay on that I found was 60 seconds. No way that is long enough. Perhaps I just need to shut our bedroom door. Anyone have any other ideas?
