"It's the same thing, but crazier," Garner said of the addition of Seraphina to the family. She was born in January.
Garner and Affleck are also the parents of 3-year-old Violet.
"Everything's going really well. Everybody's happy and healthy. It feels like it's only one more, but it feels like three more," Garner told reporters in Los Angeles recently, while promoting her new romantic comedy "Ghosts of Girlfriends Past." "The second child is easier, the experience is easier with the second, but the overall thing is just chaos; happy chaos."
Garner added she is grateful she has a job that allows her to spend so much time with her young children.
"I work really intensely for a while, but in a way and in a place where people are very respectful of me and my kids," she said. "And, if I have to take a break and feed a baby, they let me, which isn't always the case for women in the corporate world. I have help and I have the support I need. I have a great partner in raising kids and he is super-involved in there with me and then I just got to take nine months off from work, which, who gets to do that? So, so far, so good."
