While the couple dote on their two-year-old son Flynn, Miranda said their hectic schedules have prevented them from even thinking of expanding their family, reported People magazine.
"We are really enjoying our time with Flynn at the moment. He's such a ball of love and he's so wonderful. And we are both so busy that I think it's nice to have that time together and not rush any other babies for now," Kerr said.
"We keep in touch with lots of Skype. Especially now that we have our son. I'm not much of a talking on the phone person. I prefer to text. It's always very hard to get me on the phone," she added.
Despite their busy schedules, Kerr, 29, and Bloom recently found time to throw a huge bash for Flynn's second birthday.
"It was a lot of fun ... And it was a really special celebration. We had a little bubble machine and the kids loved it. We also had little bunny rabbits and chickens," she added.
