If anyone knows anything about Mary, she loves mud. Gritty mud, slimy mud, brown puddles with who-knows-what inside, she just can't get enough mud. We were in the front yard and she slathered the stuff on her and ran around in circles- "Look, mom!! I a bird!" she exclaimed. Brother, on the other hand, gets rather disgusted if he has anything, even crumbs, on his hand. He has a fantastic time chasing his sister, which gets them both hysterical.
Oh, and for the record, no, I don't always allow Mary to run around like a lunatic in her underwear in the front yard. But this day was an exception (which I suppose I allow maybe too much :)
