From the Daily Mail:

Mrs Cameron, 38, is said by friends to be 'knackered' as she prepares for the birth of her fourth child. Her fourth child is due in September and although at 36 weeks, most airlines would allow her to fly, she won't be accompanying her husband to the US this week:

Most airlines allow pregnant women to fly up to and including the 36th week, provided the pregnancy has been straightforward. Mrs Cameron's baby is understood to be due in early September, meaning she could still travel if she wished.

If she were a real American, she'd not only be flying in a month's time, but experiencing labor on two transcontinental flights! Honestly, these women who actually behave according to the usual rules of human biology, time and space. They really should be refudiated.
