Our toddlers have now grown to a place where they have worked with the indiviual materials in small lots with very close guidence from 1 1/2 years old. Now 6 months later with two new infants, all the Practical life activities have been moved together into the front room. (originally the nap room) This is now the “Classroom” The older children whom have had previous work get to wonder in here and do as many activities as they want. I let them go in during the naps of the infants so I can be with them. One toddler who is 3 can be trusted for short intervals in the classroom by himself while I am watching from the other room.
