Kristen Wiig is "nervous" about leaving her twins when she goes back to work again, but she's hoping to strike the balance successfully.
"Right now, I'm not going to an actual set, but because of all of this stuff, I'm not as present as I would like to be," said Wiig, 47, referring to media days promoting her upcoming comedy, Barb & Star Go To Vista Del Mar.
"And it's really hard because I'm always convinced they'll forget who I am if I'm gone for a day," she added, laughing. "I have looked at my children and been like, 'I am your mother.' "

The Saturday Night Live alum also admitted that she's "nervous" for the days when she actually has to leave home and go back to filming.
"There's something really nice about just being home with them all the time," Wiig said. "But they're really young right now, so I feel like I have that as an advantage — they don't really know when I'm not there."
"But that time is coming and I'm gonna do my best to balance, and they will come first," she added.
