In a child care facility, children have opportunities to learn in addition to being B. cared for in a safe environment.
Children aren't necessarily with others all of the time because sometimes they want to sit alone for a while; they aren't under constant supervision because the carer may leave them to play alone for a bit; they are definitely not completely independent because their carers have to take care of them and watch over them.
