The TV personality, who is the adopted daughter of singer Lionel Richie, has 4-year-old Harlow and 2-year-old Sparrow with Good Charlotte musician Joel Madden.
In regards to her eldest's interest in the fashion business, Richie said that she wants Harlow to obtain her innocence as long as possible.
She told Flare magazine: "She has no idea that she has two lines named after her - I try and let her be a kid."
Richie, who is a celebrity mentor on NBC's Fashion Star, added that she is constantly talking about sheltering children from the spotlight.
She explained: "I was just talking to a friend of mine who has two little girls about a certain singer whose name I won't mention.
"He was really upset, saying she wasn't a good role model for his kids. But here's the thing: that girl is 20-something, so she shouldn't be a role model to your little girls. She's human, and it's unrealistic to put people on a pedestal and expect that they're not going to make mistakes."
