First and foremost is your child's age and developmental stage. The older a child is, the longer he'll be able to play alone. For example, at 6 months, a child may be content by himself for 5 minutes; at 12 months, for 15 minutes; at 18 months, about 15 to 20 minutes; and at 2 years, for about half an hour.
Examples of activities within the developmental stages of play are: solitary play: a child playing with blocks alone in a corner. parallel play: two or more children playing with blocks near each other but not talking with each other.
