The child doesn’t seem to be dressed in anything but drawers, either.
Not supporting what she did, but during the summer, back after I learned to walk, and before I learned to read..... It was heroic to get me to wear any kind of clothing. Heck, I'm not too big on clothing today during the summer months. I do try to cover the fiddly bits, mostly.

Perhaps it was HOT outside....just a diaper on a little kid is still legal.....
