Childhood development experts generally say that a reasonable attention span to expect of a child is two to three minutes per year of their age. That's the period of time for which a typical child can maintain focus on a given task.
Average attention spans work out like this:
2 years old: four to six minutes
4 years old: eight to 12 minutes
6 years old: 12 to 18 minutes
8 years old: 16 to 24 minutes
10 years old: 20 to 30 minutes
12 years old: 24 to 36 minutes
14 years old: 28 to 42 minutes
16 years old: 32 to 48 minutes
