Prince William and Kate Middleton have a due date for their second child.

The family announced yesterday, that the second royal baby will be due in April. The gender is still a secret to the public but this is the first time a royal baby had a confirmed birth month. William and Kate's first child, George, was born in July 2013 and he is third in line for the British throne while their second child will be the fourth in line, regardless of gender.

Prince Charles is still first in line after his mother, the Queen, with Prince William following him then his son, Prince George and then their second child, no matter what sex the baby is. Britain officially changed their law last year of only men being able to rule, so if the second child is a girl, she will still be automatically fourth in line. Prince Harry will now be pushed down to fifth.
