The Hollywood couple welcomed baby daughter Daisy into the world on Tuesday, which happened to be International Day of the Girl Child - an informal holiday launched by philanthropic organisation United Nations Women.
Wilde took to Instagram on Saturday to announce the exciting baby news, posting an adorable picture of the newborn and adding the caption: "There goes the neighborhood. Daisy Josephine Sudeikis. Born, like a boss, on #internationaldayofthegirl."
The first precious photo Wilde shared of her and Sudeikis' daughter features the tot sprawled out in the middle of a giant stuffed animal sheep pillow. Baby Daisy is a little sister to the couple's two-year-old son Otis.
