The story of Montessori is in great part the story of the the Kinesthetic modality.
Even when babies put an object in their mouth, the angle of the jaw and the tension required to hold the object contribute to this basic information pool.
On the one hand, we want to provide babies with as many opportunities as possible to examine many different referents.
On the other, the parent (or caretaker) has to be constantly alert to the dangers to the child that objects can bring.
Like a referee, they most constantly hover over the baby as he/she explores the objects of the new world. It's an intensively grueling and fatiguing task for the parent, but the rewards are great!
The story of Montessori is in great part the story of the the Kinesthetic modality. The Montessori approach stresses hands-on exploration at an early age.
