Montessori Quote
At seven years begins a physical and psychological change. The child of seven has a different psychic attitude. Physically nature puts a sign that is obvious. The pearly teeth of the little child fall out, they are replaced by large, strong, deeply rooted teeth; the curly hair becomes straighter and darker; the fat chubby body becomes gawky and thinner.
Maria Montessori, Citizen of the World, p. 36
