Having announced last month that a new sibling
is on his or her way to join their daughters Violet, 5½ and Seraphina, 2½, experienced parents Jennifer Garner
and husband Ben Affleck
sure know how to cope.
"Snacks. We have snacks in the car. We have candy in the car," the actress, in Toronto where her well-received new movie, Butter
, played the film festival, tells USA Today
More advice? "Find ways to be as comfortable as possible and just go with it," says Garner, who wowed in Valentino. "It's not an illness, being pregnant. I'm in the easiest part of it."
Besides the satisfaction of having a happy family
, Garner is also delighted with the response to her movie.
"Pleased doesn't begin to describe [it] – relieved, grateful, surprised, shocked when we got the first big laugh," she says.
