Donna and Paul DeRossi Own an Agricultural Farm in the Outskirts

Donna and Paul DeRossi own an agricultural farm in the outskirts of New Jersey. Their son Ron, who is 13 years old, helps them every day by watering the saplings. Neighbors saw Ron working in the field every day and informed Department of Labor about this and complained of child labor. Have Donna and Paul violated the law under Fair Labor Standards Act (FLSA) by allowing their son to work on the agricultural farm land?
