Big Brother Bed

Cash asked to go to bed tonight - in his big boy bed. We were getting dressed in the nursery and he kept saying "in there, in there" so we went into the other bedroom and he said, "go to bed in here". Ok, if its that easy i'll be really excited. Something tells me that we aren't going to get off that easy but at least he understands that you sleep in that bed and not just jump around on it.
