Sarah Michelle Gellar feels responsible for "everybody's children".
The 38-year-old actress - who has kids Charlotte, five, and Rocky, two, with husband Freddie Prinze Jr. - is working with No Kid Hungry, which aims to end childhood hunger in America, and did so in order to help others, and also teach her own kids about "social awareness".
She said: "You realise when you become a parent that it's not just your children you're responsible for, it's everybody's children.
"I really looked for something that I could do on a local and national level that involved children, and also someplace that I could introduce my children to social awareness.
"It can't just be me saying to my daughter, 'There are hungry children out there.'
"I need her to understand that those hungry children are next door, and that this is a real problem. I think the most important thing about No Kid Hungry is that they don't just say there's a problem -- they have a solution."
The organisation works to ensure all children in the US have access to healthy food in school and at home through a variety of initiatives, and the 'Buffy the Vampire Slayer' actress hopes to echo their messages when it comes to teaching her own daughter about making healthy choices.
She added in an interview with People magazine: "I want her to love food, and to learn that not everything comes out of a box or a vending machine.
"I think if you involve kids in the process [of choosing healthy foods], and you make them understand where it comes from and how it's grown, they take ownership. That's what you want them ultimately to do -- take ownership of their bodies and their world."
