Use the poop, Luke
Both of our children potty trained several years ago which was unquestionably a Good Thing. And yet I’ve said and I still believe that, if it were possible, I’d have suspended or slowed their aging so that I could have enjoyed every nuance of their newbornness more completely. Not that I miss diapers and their contents; on the contrary, newborns and toddlers are so wonderful that I’m willing—literally—to put up with their shit.
