Altered Voices

摘要

The baby is a few months old. His earliest cries are short, his lungs too small to produce the prolonged wail of a toddler. A few months later, he can pull in enough air to elicit a sort of chuckle. And by 6 months, he's trying out vowel-like sounds - wuh, wuh, wuh. Soon, he's combining consonants and vowels and repeating them. Nyah, nyah, nyah, he says with evident glee. The baby has begun babbling, as large a developmental milestone as sitting or standing.
