Infants need to be free from restraints in order to work on these skills. Some skills need to be demonstrated by the adult first and then are learned through independent practice. For example, the educarer might stack three or four blocks and let the infant knock them over. Soon the child will be stacking the blocks. The most important part of a well-run infant program is a trained educarer.
Flexibility is also necessary.
We must be able to meet the immediate needs of the child. Infants must be able to see us as trustworthy. They can recognize insincerity very early in life. The Montessori philosophy is something that can be carried within us and put into practice without the purchase of gizmos and expensive equipment. In fact, the simplicity of this philosophy enables an infant program to be developed with little monetary output for fixtures.
