A "Young Child Community" serves a larger number of children from around one year to 2+1⁄2 or 3 years old.
Montessori classrooms for children under three fall into several categories, with a number of terms being used. A nido, Italian for "nest", serves a small number of children from around two months to around 14 months, or when the child is confidently walking. A "Young Child Community" serves a larger number of children from around one year to 2+1⁄2 or 3 years old. Both environments emphasize materials and activities scaled to the children's size and abilities, opportunities to develop movement, and activities to develop independence. The development of independence in toileting is typically emphasized as well. Some schools also offer "Parent-Infant" classes, in which parents participate with their very young children.[20]
