Women who have two or more children always blow my mind. I look at them in awe and constantly wonder, “How do you manage more than one child at a time by yourself? Where do you get the energy?”

But more recently there’s another point for me to ponder. My son has apparently developed a finely honed sense of when we are having sex. And then he bursts into the room.

You’ve read about his (ok Marc and my) exploit two weeks ago, right? Well, if not, scroll down. I’ll wait.

Just last night around midnight, he barged into our room yet again and caught us in a most compromising position. He was half asleep. And again, today he made no mention of it.

How do people have sex when they’ve got a child with this kind of radar? We’re not loud or anything. His bedroom is the farthest one from ours. How does he know? Does he wake up in a cold sweat and think, “I sense my parents are conspiring to give me a sibling. Must. Stop. The. Madness.”

Look at that self-satisfied smile. It says, “Hey, I’ve been playing my cards right. As you can see, no siblings mean mom and dad have money to take me to sweeeeet places like this! Dude, I just bellied up to the bar that’s IN THE POOL! I’m livin’ the good life.”

Doesn’t he know that really “harshes the buzz” for mom and dad. We’re parents now. We now pour all of our extra money, energy and time into him. Doesn’t he realize that the only fun thing we have left is having sex? He obviously doesn’t realize that if mom and dad aren’t gettin’ lucky he’s gonna end up with some really pissy, short-tempered parents.

We REALLY need to get that door fixed.
