"Her Royal Highness and her daughter are healthy and doing well, and the family are enjoying spending time together with Athena's older siblings, Wolfie and Sienna."

Beatrice's baby was not expected until "early spring," according to a previous statement from Buckingham Palace announcing her pregnancy. The baby weighs four pounds and five ounces, per the palace.
