It's a bit of a two parter. First she starts with a typical wah-wah. A few wah's and it's clear what she wants.
However, if she's super hungry the wah's link together and her mouth won't close long enough to wah properly. Then she sounds like a bad evil laugh. In fact it sounds exactly like The Count from Sesame Street. Wah-ah-ah-ah-aaaaah. She even gets the warble right. I keep expecting a crash of random lightening after each cry.
Instead I get one...one hungry baby. Ah-ah-ah-aaaaah.
