Until the first year of life infants cannot produce coherent words, instead they produce a reoccurring babbling sound. Babbling allows the infant to experiment with articulating sounds without having to attend to meaning. This repeated babbling starts the initial production of speech. Babbling works with object permanence and understanding of location to support the networks of our first lexical items or words. The infant’s vocabulary growth increases substantially when they are able to understand that objects exist even when they are not present.
