Rollin Rollin Rollin

Sam can now roll from his back to his stomach.  He did this trick for the first time that we're aware of sometime prior to five AM last Wednesday morning.
We know that it was prior to five AM because five AM is when he woke us up howling after he managed to get both legs through the slats of his crib.  So he was on his stomach, through the bars up to his crotch on both legs, with his legs dangling over the floor.  Of course, this is an untenable position, and he indicated as much by screaming his head off.
The roll over and slide through the slats is actually Sam's second trick.  His first trick in the crib was flat spins.
We had a huge storm a couple of weeks ago, which Kate was worried would wake the boy up.  It didn't.
Around one AM we lost power in our house, so we lost air conditioning and fans and the monitor.  Then Kate worried that the absence of the fan in Sam's room would wake him up.  It didn't.
At around five thirty the power came back on.  The sudden influx of noise from the AC and fans and whatever didn't wake Sam up either.  It did, however, wake the monitor up.
At about 5:15 we heard a thump.
Kate:  Did you hear that?
Me:  Yeah
Kate: What was it?
Me:  I dunno.  Maybe a cat?
Thump
Kate: That came over the monitor.  Could there be a cat in his room?

That's always a possibility of course. 
We have two cats.  Cats are agents of Satan.  Both of them.
We have Fred (our primary cat) and The Monkey (our auxiliary cat).  The Monkey is relatively young, and kind of a spaz.  She hasn't learned the cat magic of dematerializing on one side of a door and then rematerializing on the other side.
Fred has that one down.  I can't tell you the number of times I've pulled laundry out of hamper around Fred who was sleeping on the pile, loaded it in the basket, and taken it down to the washer (there's only one path to the washer in our very small house) only to find Fred sitting on the washer when I got there.
So, the thump could certainly have been a cat.

Mark:  Of course there could, but I think he'd have come in here (The cat, not the baby) a while ago.
Thump Thump
Kate:  I'm going to see what that is.

It was Sam.  He had spun himself 90 degrees, which means that he was spanning the short part of the rectangle.  This set him up to kick the the crib wall right under the monitor.

The monitor is now sitting on the window sill.

We saw the doc last Friday for a routine checkup.  Everything is still good.  We got the go ahead to start solid food, we're still figuring out how we want to approach that.  Sam got another round of vaccinations, which is never fun, but he handled the shots pretty well.  He's just short of fifteen pounds and around 26 inches long.
