Growing Up Quickly

So I caught Asher standing yesterday.  We have a drawing table for the kids in the kitchen and he had crawled out there to it.  He was awfully quiet, so I thought I would check on him and he was standing at the drawing table.  Somehow he had managed to pull himself up, of course I freaked out because our kitchen is really, really, really hard tile (as opposed to the really soft tile ;)) and all I could see was him falling and hitting his head on the floor.  I know he's advanced because I compare him to what Calvin was doing and he's a few months ahead, but it still throws me for a loop every time he tries something new.  Now, if only he would get back to sleeping well at night...I can always hope, right?
