2-month-old baby leaves mother speechless!

At two months old newborn babies are not yet able to speak, but they can and do begin to understand the melody of language. For example, they are able to distinguish an angry tone of voice from a cheerful one and to react accordingly. 

This child can be considered an extraordinary exception to the rule! The child's mother says the word "Hello" several times and then unexpectedly, the child repeats the word with exactly the same intonation, unequivocally!
