Sucking Is a Natural Instinct

It has been demonstrated that the baby already sucks its thumb when it is in the maternal womb, learning a practice that, once it has been born, it will allow it to feed itself and, therefore, to survive.
Sucking also satisfies the psychological need of the newborn baby to be reassured and gratified: sucking calms and reassures the baby and consequently creates a more peaceful family environment.

Sucking in fact regulates the production of serotonin, which helps to create a sensation of peace and well-being.
In particular, sucking the nipple not only satisfies the indispensable nutritional function, but it also represents an important moment of contact and interaction between mother and child.
The instinctive sucking need, however, makes the baby seek and use instruments different from the breast to satisfy its need to be reassured (thumb, blanket, toys).

Non-nutritional sucking is therefore important from the psychological, paediatric and orthodontic point of view.
