Early teachers, also known as early education instructors, are teachers who are engaged in consultation, guidance, consultation and teaching of infant care, education and parenting for 0-6 years old, and do not belong to knowledge education; Different from kindergarten teachers, early education not only educates children, but also educates parents, especially mothers. Early education can be divided into preschool teachers, parent-child teachers, teachers who feel integrated, Montessori teachers, Orff music teachers and home-based early education. As a professional education, early education involves infant physiology, psychology, pedagogy, nutrition, brain science, female psychology, thinking science, business science, learning science, family education and other disciplines, which is beyond the understanding and mastery of ordinary parents. So the early teachers were quite professional.
