I see no reason why babies can't just be naked. I stay home with my son, and when he wakes up, I strip him down to his diaper to eat, let him run around naked, and we only dress him in clothes if we go somewhere. Occasionally I put shirts on him if it is chilly, but some days he stays naked. I do put a shirt or something on him for naps, and pjs at bedtime just so he wont get cold. He went through a stage of taking off his diaper and peeing everywhere, so I bought a package of onesies. He can't get those off quite so easily, although he can do it. Now that mine is potty training though, he won't pee on the floor, so if he wants to run around without his diaper I let him. I sure do save a lot of time not worrying about laundry, and a lof of frustration of keeping him in clothes. He knows we wear clothes in public, but if you were just stop by my house unexpectedly, chances are he'd be running around naked. This is just not a battle that I choose to fight, or is even on my radar really.
