Sunday Rose Kidman Urban is already feeling the love from her grandmother, Janelle, and her auntie, Antonia, both of whom traveled from Sydney, Australia, for her arrival.

“The birth of Nicole and Keith’s daughter is such wonderful news and a beautiful addition to our family,” Nicole’s sister, Antonia Kidman, tells PEOPLE. “We’re all absolutely thrilled with the new arrival.”

The Kidmans arrived in Nashville over the weekend from Sydney while Nicole’s father, Antony, stayed behind to watch over his other grandchildren.

Nicole and Keith’s baby girl was born Monday morning in Nashville and weighed 6 lbs., 7.5 oz. The pregnancy was first announced in January. Kidman has two other children with her former husband Tom Cruise: Isabella, 15, and Connor, 13.

Antonia, who has four children of her own, and her mother plan to remain in Nashville for the next several days.
