"People always say you don't realize how much you can love somebody until you have a kid," Roper told Iaconetti, who also co-starred with her on "Bachelor in Paradise." "It's wild!"
"There was this one night where she was up every hour and I got no sleep and I was just crying the entire night and I'm like, 'I can't even be mad at you because I just look at your face,'" she gushed. "It's just, like, this crazy love.'"
Roper said the "crazy love" she feels for Emerson also extends to Tolbert and their dogs.
"It makes me love everything even more," the star said. "I love Tanner more. I love Emerson. I love my dogs more. Like, I thought I'd come home and I'd like, 'Oh, you guys are just dogs now.' But it makes me love them even more."
"Your heart is so full, its unbelievable," she explained.
Roper gave birth to Emerson on Aug. 17.
She shared new photos of her baby girl this week on Instagram, including a picture of herself, Tolbert and their daughter in bed.
"She doesn't look like her daddy, at all," the star captioned the snapshot.
