The couple, who play Snow White and Prince Charming (also known as Mary Margaret and David), welcomed baby Oliver in May, while their TV characters had a son named Neal late last season.
“I haven't started acting yet this year,” Goodwin told reporters during a recent “OUAT” set visit in Vancouver. “I just show up exhausted and have to be exhausted Mary Margaret.”

She added that the writers and producers will ask, “'How are you?' I'm like, 'I'm tired.' And they're like, ‘We have a great episode for you coming up.’”
The 36-year-old is also using her new mom skills on the set. Goodwin explained that “OUAT” uses eight babies for her son Neal, adding that she can definitely tell them apart.
“That's a new mom quality I have,” Goodwin said. “I used to be like, 'babies look like babies.' And now that I have a baby, I'm like, how does the audience not notice that in every shot, this is a different kid?”
Ginnifer also touched on Mary Margaret’s parenting style, explaining that she didn’t feel deserving of baby Neal. “She believes that she needs to be like this ridiculously, unrealistically perfect, multi-tasking mayor mother... she's also scared to ask for help.”
