Question: how much alone time do babies need?
Answer: 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.
