It isn’t baby talk.  Baby talk is when you speak like a baby to other grown-ups, or older children.  The above-described speech was traditionally called “motherese” but is now called “infant-directed speech” or “parentese.”  Babies’ brains respond positively to this type of speech and their whole bodies respond to chanting and rhythm.  If you put an infant on your lap and bounce her to the rhythm of music or a chanted tune, the infant will nod her head, bounce her body up and down, and kick her legs and arms to the beat.

We can use this as a means of supporting mathematical concepts with infants.  Through repetitive chanting of songs, infants will begin to internalize number words and concepts.  If you sing “The Wheels on the Bus” with an infant in your lap, you can encourage the notion of “round and round” (spatial thinking) and “up and down” (more spatial thinking).  If you chant, “This Little Piggy” touching each of baby’s toes one at a time, singing,  “this little piggy went to market…” you will encourage “one-to-one correspondence.”
