1. Dashiel Edan Jovovich-Anderson: Ukrainian-born actress Milla Jovovich gave birth to her second baby on Wednesday. Just a few hours after the birth the actress released this adorable snap of her newborn. Next to the photo she wrote, “We are so proud to announce the birth of our second daughter Ms. Dashiel Edan Jovovich-Anderson today!!! She is 7lbs. 10 oz. and 20 inches long! We love you Dash!” If you’re wondering what that unique name means — well, it actually doesn’t mean much. The name is thought to be derivative of the old French surname “de Chiel” and transformed into Dashiel over time. (via @millajovovich)

4. Ioni James Conran: The award for most photogenic baby most definitely goes to model Coco Rocha’s newborn girl. Coco Rocha announced on Instagram that she and her husband welcomed their first daughter Ioni James Conran this past Saturday. She was only hours old when her first Instagrams were shot, but she seems to have already mastered some total model poses – it’s no wonder she’s an instant Instagram star. (via @cocorocha)
