My daughter likes to pretend she's an animal or another person. Every day it's something different. Every day the voice that accompanies the pretend person or animal is usually a high pitch squeaky voice. My daughter is 3 and at that age most girls (I say most because there is one playmate of hers I swear sounds like Lauren Bacall) have naturally high voices.
Lord help me today was one of those days where everything coming out of her mouth sounded like incoherent bird chirps.
