I posted this on FB (that's Facebook for you nonbelievers), but it was so funny that I still laugh when I think about it, so I'm recording it for posterity in Jessica's blog.
A while ago, Jessica developed the amusing habit of saying "Alert! Alert!" when something was happening that she thought needed adult intervention. Well, a couple of weeks ago, Xander had a poopy diaper and ran upstairs when I told him I wanted to change it. Within a couple of minutes, we heard Jessica shouting from upstairs, "Stink alert! Stink alert!"
