The 34-year-old star, who recently have birth to her second child with actor husband Pete Sarsgaard, wants to know how to bring up two youngsters at the same time, reported Contactmusic.
"I am 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," Gyllenhaal said.
The actress has a 5-year-old daughter Ramona and gave birth to Gloria Ray last month.
"Peter was joking with me the other day. He said, 'How are either of us ever going to work, ever?' We have figured out pretty well how to do it with one. At first we would take Ramona with us. Now she is in kindergarten and it is important that she is settled. I wouldn't take her out for any old thing," she said.
