Jason Biggs 'Was Upset That He Can't Breastfeed,' Says Jenny Mollen

June 17, 2014 -- When Jenny Mollen and Jason Biggs welcomed their son Sid, in February, the actor had read all the books and done all the research.

Though he might have been the prepared one, Mollen could still do what her husband couldn't: feed their baby.

"Jason is a total mom. He was upset that he can’t breastfeed," she told ABC News. "For a while he was like, 'Wait, can’t you pump so that I can give him the bottle?' He's all about it."

These days, they both could use a helping hand: Mollen, 35, is in the middle of a tour promoting her new book of essays, "I Like You Just the Way I Am," along with Biggs, 36, who's currently starring in season 2 of "Orange Is the New Black." However, when their schedules cause them to part ways, Mollen explained that she'll take Sid.

"I’m trying to make peace for the fact that I don’t have a nanny so it’s going to be a lot of one-on-one time with my mom," she said. "That’s what I’m dealing with!"

Her mother, incidentally, is a character in the book of comedic essays that documents various phases of Mollen's life. One of the only important people in her life not in it, she said, is Sid, who earned his name after appearing "tougher" than she expected at birth. (Had he been the blond-haired, blue-eyed child she thought she'd have, his name would have been Miller.)

"He looked tougher than I expected. He had a full head of hair, a pronounced nose and these really judgmental eyes. He’s not this sweet baby I thought [I'd have]," she explained. "So we decided on Sid, because Sid Caesar had just died and I liked Sid Vicious and he just felt like a little old man in a pinstriped suit named Sid, betting on the ponies."

And while she didn't necessarily prioritize having a child, now that she's a mom to Sid, she said she can't imagine her life any other way. However, she still hasn't lost the edge she's seemingly passed down to him.

"The minute I had him, it's so overwhelming. It sounds so cliché but you immediately are just so attached and thinking, 'I want to protect you and love you and give you everything you want,'" she said, before catching herself sounding sentimental. "It'll end up making him a total d***!"
