During Aaron's first six weeks or so in America, his stomach made him howl every three hours. Day and night, every three hours or so he would cry like he was the last baby on earth, and increase in volume until we got him his bottle. Needless to say, it was a stage in our lives marked by sleepless nights, endless days, and frayed nerves.
As we've introduced solids into his diet, and as he's gotten used to us, our home, and his schedule, he's lasted longer between feedings, and hasn't had to turn up the volume or the body language when he does get hungry. He can still bring the heat at 98 mph, but lately it's the exception and not the rule.
In place of these blood-curdling screams are new noises. He gurgles, babbles, and once or twice we swore he said something approximating "Mama." I suppose we should be more excited than we are that he's becoming so verbal. I think we're just more excited to hear these sorts of sounds than the other ones, which are evolutionarily designed to be impossible to ignore.
