When you plop Genevieve in her high chair and she realizes that the food's coming, she starts clenching and unclenching her little fists and wiggling her fingers. You get about five clench/unclench cycles to get some food in her craw before she starts to cry.
Julia, on the other hand, uses her words to express her desire for food. Well, her words and her eyes. If you have something she wants - the last strawberry, a piece of bread with butter, a cookie just like the one she finished, et cetera - she looks intently at it and say, "Why am I staring and staring at [e.g.] Mama's pineapple?" Inevitably (because who can resist?) she gets at least some of the coveted item. The other day, though, I laughed when she was "staring and staring" at something on my plate, and I said, "I think you're angling for a bite." This new construction caught her fancy, and for a few days she said, "Why am I dangling for a bite of [e.g.] Daddy's broccoli?" I corrected her a couple times, and now she says it right, unless she's trying to be funny, like last night: "Why is Genevieve dangling and dangling for a kiss?"
