The baby does not master verbal communication, but through voice and crying, it is able to express its feelings and primary emotions, using for this purpose, the voice's different colours, depending on intention: seducing or irritation, concern or only a call for attention, as well as the different types of cry, which many recognise the differences quite well, namely, the hungry cry, the sleepy cry, the uncomfortable or the tired cry. Before communicating verbally, we communicate through small intonations or vocal nuances whilst using our body.
