Marla Sokoloff is officially loving two little ones: her baby girl is here!

The actress and her husband, composer Alec Puro, welcomed their second child on Friday, March 13, her rep confirms to PEOPLE exclusively.

Daughter Olive Mae Puro arrived six weeks early in Los Angeles, weighing 4 lbs., 10 oz. and measuring 18 inches long. She joins big sister Elliotte Anne, 3.

“Someone decided to join the world just a wee bit early. She couldn’t wait to meet us,” Sokoloff, 34, tells PEOPLE, adding that Olive will remain in the NICU for the time being. “We are so in love!”

In her November blog, Sokoloff — who announced her pregnancy in October — wondered what her future as a mom of two would look like.

“For the past 2½ years plus, my little girl has been my everything and when I look at that face, I’m positively blown away by her,” she wrote.

“There is so much beauty and excitement that’s about to come my way, and I’m truly feeling way more blessed and lucky than I could have ever dreamed of.”

But although the soon-to-be big sister was tackling her threenage years, Elliotte was still ecstatic over the family’s future addition.

“Elliotte’s excitement for the new baby has not waned at all and I cannot wait for her to meet her new baby sister!” Sokoloff wrote in January.
