Interesting piece in the New York Times by a pediatrician who always asks parents if their baby is babbling.
The first thing to know about babble is also the first thing scientists noticed: babies all over the world babble in similar ways. During the second year of life, toddlers shape their sounds into the words of their native tongues.
The word ''babble'' is both significant and representative repetitive syllables, playing around with the same all-important consonants. (Indeed, the word seems to be derived not from the biblical Tower of Babel, as folk wisdom has it, but from the ''ba ba'' sound babies make.)
