Game and toy as an engine of development in the child from 0 to 3 months. At this stage the game will help us to develop the prerequisites of communication, which are three: cenestesica sensitivity, perceptive and expressive capabilities and rhythms and scheduled time. The primary expression of the cenestesica sensitivity is body contact (the mother with the newborn) which marks a tonic dialogue. It’s an emotional harmony, that will be necessary to communicate on another level than merely the transmission of messages. Margaret Bullowa stated thereon that the communication we have given too much importance to the code, to the details of transmission and reception, but that not we had passed by the minds that in communication there is other things that make reference to their global properties and that make it possible.

The latter concern more to be in communication with who and how to communicate. The second prerequisite are the children’s receptive and expressive capabilities involving vision and hearing. The first is the ignition switch, preamble to a (possible) interaction; the second is the processor of the tonal and rhythmic background that surrounds all communication. It must be borne in mind that any kind of visual, auditory, olfactory, tactile perception that the child has of people will start its expressive manifestations because the child’s perceptual system is integrated to its system of action. A third prerequisite are neonatal rhythms, i.e., the scheduled temporary which characterized several of the toddler behaviors. Food suction is particularly interesting because, unlike the breathing or heart rhythms, it is an activity a Duet between the creature and the mother. K. Kaye (1982) has made a microanalysis of the same showing how to insert psychological communication function in a purely biological function (power) and after analyzing the duration of breaks and the conduct of mothers during the same, discovered that those learn to adjust the optimal pause time so the child continue their food.
