Proper stimulation , Imitation of natural sounds in words : swish , ticking, clink .
Imitative harmony is a figure close to the onomatopoeia and alliteration and can play some hearing and even emotional effects by repeating certain phonemes.
For children and babies , not just a series of exercises , massages and caresses ( no clear purposes).
It is much more than that, it is to know every step of the process of formation of childhood brain structure.
