When we go to the beach (which we do often) DD7 has always preferred to lie in the sand on her belly, slither along, and throw sand on her back as she goes. She looks very much like a sea turtle on land. I have umpteen photos of her completely breaded, from head to toe, starting from age 0. I tell people, "She is grounding herself." Seriously, I think she's satisfying her sensory needs. smile
