Maggie Gyllenhaal has "no idea" how to deal with looking after two children.

The Hysteria actress - who recently gave birth to her second child with actor husband Peter Sarsgaard - intested to see how she copes with bringing up two youngsters at the same time.

"I'm curious to see how much I remember about nursing and changing diapers. About all of it. I have no idea how to do it with two. Having children is the most humbling thing you can do," the 34-year-old mother told USA Today.

The parent to Ramona, five, and Gloria Ray who was born last month, admitted that she and her partner are worried about juggling their schedules.

In her new motion picture she plays Charlotte Dalrymple, a women's rights activist in Victorian London. The Tanya Wexler-directed film revolves around how the vibrator was created. "'Peter was joking with me the other day. He said, 'How are either of us ever going to work, ever?' We've figured out pretty well how to do it with one. At first we would take [Ramona] with us. Now she's in kindergarten and it's important that she's settled. I wouldn't take her out for any old thing," she confessed.
