I've known plenty of moms who take pride in their children being spotlessly clean, women who change their children mid-play when their clothes get dirty, who are always at the ready with a wash cloth to swipe away the grime.
I take more pride in mine being dirty. There's something about their little sweaty heads smelling of copper pennies, their nails embedded with dirt, their jeans caked with mud that speaks to a life well lived.
I'm happy to get them shined and scrubbed before bed, but that night time bath is so much more rewarding when the day has been spent barefoot in the mud. And when that bath doesn't happen, when they go to sleep with their dirty little soles poking out beneath once clean sheets, I'm pretty okay with that too.
