This word in English sums up the dialogue we have with a baby, and it is something that we all do without being aware of it. Our way of carrying out this communication is natural, since we are prepared to teach and prepare our own species to develop the sense of speech and communication, but there are certain ways that can affect.
Naturally we make sounds that can stimulate the child’s reactions, for example the sound that we produce with a high voice captures attention and can even provoke pleasant reactions in the child such as laughter, and we do this innately.
The best thing you can do to work on the development of the baby’s brain even before its birth, is to take care of yourself as a mother and lead a lifestyle as you would like him to lead in adulthood, after all, he already is absorbing from you, even before being born.
