Is there a family ESTA application option for parents and children?

No. There is no separate family ESTA application option that allows parents and children to apply as one single ESTA. 
Even if parents and children are traveling together, each family member must obtain a separate ESTA approval, and a parent or another third party may complete the application on behalf of a child. 
If you are planning a trip to the United States, please make sure to apply for ESTA for all family members before departure.
