For the past almost six days, the geek has been yukking it up with museum people in Denver.

He returns tonight.

While it’s been sort of nice, as an experience with a definite end point, to be the sole caregiver, the only lap, the lone tickler, I’m exhausted.

During the second shift of baths last night, I was covered in bubbles, still recovering from the previous night’s bout of food poisioning when it occurred to me: I couldn’t do this on my own. Not forever.

So today, I tip my hat to the millions of moms who do it every day, by themselves, with no partner to relieve them. You are my heroes.
