At the beginning of summer, the boys would spend most of the day in shorts and a t-shirt, but as summer has progressed, I find myself getting them dressed less and less. Or, I'll change their diaper half-way through the day and will just leave their clothes off. It's been so warm here, and if we don't have anywhere to go, what's the point, right? Besides, they're just so cute when they run around in just their diapers.
Once we have a decent backyard, I'll even let them run around naked, but I think that will have to wait until our next house.
