The baby in Mommy's tummy

We're pretty sure she understands that there is a baby in my tummy. In fact, she spontaneously kissed my belly the other day, bringing tears to my eyes. We've been asking her if she thinks it's a boy or a girl, but her answer to that changes pretty often. We've also asked her what she thinks the name should be and her answer lately has been 'Chi chi waji'. In fact, she tonight she told me that the baby in her tummy is also called Chichiwaji. We haven't thought of very many possible names for this baby, but somehow I'm afraid Chichiwaji is going to stick.
