Just a quick update... our first babysitting experience went great! Sam did awesome. He's a pretty easy baby, generally, but I was hoping he'd be especially easy on this first go so our sitter wouldn't be like, "Um, no thanks." But that boy went right to bed on cue and didn't make a peep. Only burp was the sitter not being able to operate the TV. Which I know plenty of y'all warned me about! The hub did give a quick Remote 101 lesson (and we left the TV on), but obviously we weren't thorough enough. Our TV is not all that complicated, but sometimes the receiver will "go to sleep" and if you push the wrong button all hell breaks loose. Or, really you just lose TV. But she kept herself busy with magazines and texting her friends... so no biggie. Lesson learned for next time.
Thanks again for all your great advice!
