Researches have discovered that the cries of infants as young as three days old already reflect the language their parents speak. The study showed how certain French babies would cry in a rising melody contour such as ascending tones whereas German babies followed a descending melody contour true to their language form. Perhaps a study involving Swahili babies would reinforce this finding by revealing a percussive series of clicks in the babies outbursts.
It is quite remarkable to think that newborns have already learned the pattern of their native language just by observing their parents voices in utero. It would seem that our most rapid strides in learning take place in our infancy. Babies are like little mental sponges absorbing and analyzing vast amounts of data. Babies are also very efficient food processors and they like to poop, a lot.
We come into this mortal world having left from a much more exalted realm, a pre-mortal existence, learning and progressing as spirit children with our Father in Heaven. No wonder babies are quick studies, look where they all come from! As Wordsworth wrote, they come "trailing clouds of glory."
