Explanation:

From birth, babies have only the gestures, some sounds and crying to communicate and transmit their needs and emotions to the people around them.

The pre-linguistic or non-verbal stage is called that precisely because there are no words, what there are are sounds, approximations, twitter, babbles, cries and smiles, which constitute the first stage where children already begin to communicate, and it lasts longer or less until twelve months.

The gestures and sounds reveal the baby's mood, as well as different needs: eating, having physical contact, changing diapers, sleeping, drinking, etc. Babies always transmit and communicate.
