You can think of this as ‘accidental’ communication. A good (and simplified!) example of this is a baby crying because it is hungry. In the first few weeks, the baby simply cries in response to the discomfort of hunger but, crucially, the parents interpret the cry as a request for food and give the baby a bottle. Over time, the baby begins to learn that crying results in being fed and starts to do it with the intention of getting food. This is the beginning of deliberate, planned and intentional communication.
