The 'Buffy The Vampire Slayer' star - who has Charlotte, seven, and Rocky, four, with her husband Freddie Prinze Jr. - says her children won't be following in her footsteps as they suffer from stage fright.
She said: "It's different because I wasn't the child of someone that was in the public eye, and so unfortunately I think the rules are different.
"I think there's a very different pressure for 'the children of' ... They can decide what they want to do for themselves. I'll never push them. But, in the meantime, they have to stick to schooling. My kids have too much stage fright anyway."
The 39-year-old actress has had a great marriage to Freddie, 39, and says the secret to their successful relationship is to "put the effort in".
She added to People magazine: "It evolves daily, and anyone that tells you that relationships aren't work isn't in a real one - and that goes for married couples, friends, family. It takes work. We think we're so connected now because of these different devices, but ultimately we're becoming more and more disconnected.
"It's about putting that effort in, whether it's a girls' night, whether it's making the most of any moment. My partner and I believe in that. One of the reasons we started [Foodstirs] was to spend time together."
Meanwhile, Sarah previously revealed Freddie makes her a better person.
To mark their wedding anniversary, she wrote: "#happyanniversary I love you not only for what you are, but for what I am when I am with you. I love you not only for what you have made of yourself, but for what you are making of me (sic)."
