The concept of sensitive periods is a foundational principle of Maria Montessori’s early learning philosophy. According to Montessori, the term sensitive periods describe windows of time in which an inner compulsion drives children toward specific activities or interests. During these times, children can learn specific skills and concepts with more ease than at other times.
