Schwarzenegger Pratt is the eldest child of Arnold Schwarzenegger and Maria Shriver, and has three younger siblings, Christina, Patrick and Christopher.
She continued, "For my husband [Chris Pratt] and I, it’s really important to be able to just instill that sense of family and the importance around family. And also giving them privacy and just being able to raise them with good values and faith and family is really important."

"Unless they wake up in the middle of the night at the same time," she added, laughing. But overall, she is happy her kids are close in age.
"It’s really special because my girls are the same age difference as my sister Christina and I, so it’s like bringing out all the old clothes, matching them, doing everything just like my sister and I had it," Schwarzenegger Pratt said.
She added, "My mom literally saved everything from our childhood, like all of our matching outfits, all of our toys, all of our books. So I’m literally recreating all of these pictures with my two girls."
Schwarzenegger Pratt is also an author, and just released her children’s book, "Good Night, Sisters."
