I could care less if they aren't dressed "right". My DH wears exercise pants most weekends because he works all week & dresses nice for that. He's tired & that's just how he chills out. I have a problem when the parent is literally dirty. Like covered in dirt, smelling like BO or cat pee. That's nasty.
If we are just running to the store quick I don't see the point of changing myself or my ten month old DD out of pjs,...as long as they are not covered in food, dirt, etc,...yup, I'm a stay at home mom, and I tend to be lazy every now and then. Who cares? As long as she and I are bathed and taken care of. Clothes are clothes.
