-When do we start learning language?

-What are some features of child language?

We start learning language as an infant by crying and fussing but that sort of communication can only get us so far, the baby needs a better way of communication and starts making sounds. By 11 to 12 months, the baby is mimicking its parents and is starting to produce words and then joining them into short 2 word phrases. (More milk) By the age of 3, most babies can produce complete sentences, and can express their needs with words at least after crying fails.

How do humans learn language?  After all the English language of any other language is so sophisticated, yet all babies learn it faster, more efficiently and in-depth than the smartest computer. Full of variations, different pronunciations and loaded with meaning and implication this amazing and unique communication skill makes us human.

Although English is extremely complicated at least for computers learning languages comes as naturally to infants "as a birds singing to attract a mate" This means most kids get enough stimulation to learn their natural language without any effort by the parents.
