The Duke and Duchess of Cambridge are as eager as the rest of the world to have a little prince or princess on board — but producing a royal heir requires careful orchestration!

"There's a window in place," a royal insider confirms in the new Us Weekly, out now. Another source explains that Kate Middleton, 30, and Prince William, 29, hope to conceive their first child anytime between the last leg of their royal tour in September 2012 and summer 2013. (This summer, the couple will be the de-facto emcees for the Summer Olympics held in London, and will be taking a royal Asia-Pacific tour in September.)
