God made dirt, & dirt don’t hurt.

Earlier last week, I caught an article listed in the “most emailed” list on the NYT website that immediately resondated with, the oh-so-rambuncious child:

“What a child is doing when he puts things in his mouth is allowing his immune response to explore his environment,” Mary Ruebush, a microbiology and immunology instructor, wrote in her new book, “Why Dirt Is Good” (Kaplan). “Not only does this allow for ‘practice’ of immune responses, which will be necessary for protection, but it also plays a critical role in teaching the immature immune response what is best ignored.”

The article goes on to talk about how ultraclean environments don’t help build a baby’s (or any young child’s) immune system because it isn’t being put through this sort of must-have training. I knew all that digging in the yard did some good!
