Bell and her husband, "Parenthood" actor Dax Shepard, are parents to 22-month-old Lincoln and welcomed their second daughter Delta just seven weeks ago.
"We don't want to be outnumbered," the 34-year-old actress said. "Until, I suppose I accidentally get pregnant and my third child watches this clip and realizes he was an accident. Sorry, honey! Yeah, we're going to cap it at two."
Shepard is already finding himself outnumbered by women in his household, Bell added.
"He likes to say that he never thought he'd be surrounded by so many women and not having this much sex," she quipped.
The actor appeared on the show in January and recalled his wife's unplanned C-section -- or as he called it, a "completely disassembled" procedure and likened it to an "autopsy" -- after being in labor for 33 hours.
"He's very dramatic," the "Veronica Mars" alum said. "He told you how traumatic it was for him but, to be honest, my perspective was -- as someone who has never experimented with drugs -- I really enjoyed it. It was kind of a wonderful experience for me. While they were doing it I was wondering what else I could get done down there... anything to get the epidural flowing."
A couple of hours after the surgery, the drugs wore off but had an unexpected side effect.
"About six or seven hours later, I'm sitting in my hospital bed and I say to Dax, 'Well, I think the epidural has finally worn off.' And he looks over and I am scratching holes in my face like a meth addict. And I'm like, it may be time to re-up," she joked.
The nurse then came in and offered her some Benadryl to help her with the scratching and put her to sleep.
"Well, what a cocktail," she joked. "Because I had a lot to say, more than when I'm sober. I started telling all these stories."
Stories that involved her taking 30-second pauses between "and" and "the." She was also fascinated by the light her cellphone gave off and used it to manically shop online.
"Thank God I didn't remember my credit card number so nothing bad happened. Honestly, a picture of a throw pillow was as mind-blowing as seeing 'The Matrix' for the first time," she said.
"I'm happy to say I'm stone-cold sober today."
"When Lincoln was born [in March 2013], the whooping cough epidemic was growing, and before she was 2 months old, we simply said [to friends], 'You have to get a whooping cough vaccination if you are going to hold our baby,'" she said, adding that she's doing the same for Delta. "It's a very simple logic: I believe in trusting doctors, not know-it-alls."
