If Madeleine's lying on the ground, Rebecca will sometimes play the attack mommy game. She walks over and throws herself bodily across mom's stomach like a pro wrestler, I think. Very cute.
Anyway, she did this today, but mom's shirt was up a little showing some belly, and Rebecca leaned in and gave her a big zrbtt on the belly, then giggled. A couple seconds later she's walking around and very deliberately sits on mom's head. I think she has my sense of humor.
