Boys Saturday night sleepover

I'm not sure how this tradition got started, but every Saturday night the boys take over our bed and I sleep in one of the bunk beds. The boys start talking about this on about Thursday ("two more days until sleepover night") and the parents start using it as bribery about the same time ("if you don't go to bed right now, no sleepover on Saturday"). I'm not sure how this is going to work when the baby comes because I'm sure he'll be in bed with me for a couple of months, and actually at this point as little as I'm sleeping right now because of being uncomfortable and running to the bathroom every 10 minutes, I'm thinking we need to blow up our guest bed. Hoisting my big belly out of Jack's low bed, or climbing down the stairs from Luc's bed must be quite the sight. Even though Kenny doesn't get quite as restful a nights sleep, I think it's one of his favorite nights of the week too.
