Supermodel Miranda Kerr and her husband Orlando Bloom are in no rush to expand their brood just yet, insisting having one child is more than enough of a responsibility.

The Victoria's Secret beauty gave birth to little Flynn in January, 2011 and she and Bloom celebrated his second birthday last weekend.

But the 29 year old admits they are waiting a while before they try for another child since they are still struggling to juggle their busy personal and professional lives.

She tells UsMagazine.com, "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."
