Gretchen Mol is a new mom – again!
The Boardwalk Empire
star, 38, delivered her second child, daughter Winter Morgan Williams, on Feb. 17 in New York, her rep tells PEOPLE exclusively.
Mol and her husband, Paranormal Activity 2
director Tod 'Kip' Williams, are also parents to son Ptolemy John, 3½.
"Everyone is happy and healthy and resting at home," the rep says. "The whole family is overjoyed."
The actress, who announced her pregnancy in November
, said the baby's arrival fit in perfectly with the show's shooting schedule.
"I'm just enjoying this time. We're not shooting now so I'm having a baby and then we'll start shooting again, which is great," Mol said. "It's really lovely to know I have a job coming and there's this little time and I can really enjoy it instead of feeling [stressed]."
