"I feel like a human about two to four hours a day," she said. On a recent afternoon, Burke felt well enough to take her sons clothes shopping and, as a special treat, to Toys R Us to pick out a toy and then out to dinner.
The babies are due in December.
"I'm excited for the boys to be here, to see what they're like and for them to be with James and Natalie ... but in a selfish way, I am also looking forward to being done," she said.
Still, she has no regrets.
"These babies wouldn't exist if it weren't for this tough decision. There are a lot of new challenges I wasn't aware of, but I kind of think that's life, too. You kind of sign up for some things, and you hope you're strong enough to handle it, and hopefully you are. And hopefully, I am."
