Speaking about her daughters as mothers, the Duchess said: "I love seeing my girls, who are exceptional. Full stop, they're exceptional."
"Then on top of that, these two little... baby Eugenie, baby Beatrice, they're looking at me with the big eyes. They look like my girls," she said of her grandchildren. "August is teaching me to play trains and diggers. And Sisi [Sienna] is just mini Beatrice, and she gets little pink tutus, because Beatrice likes to dress her up like Barbie."
Eugenie, 32, paid a touching tribute to her mother, Sarah, and big sister, Beatrice, 34, to celebrate International Women's Day on Wednesday.
