30 royal baby pictures throughout the decades

The barriers are up and the Lindo Wing at London’s St Mary’s hospital is ready to welcome back their most high-profile guest.

The Duchess of Cambridge is set to give birth to her and Prince William’s third child any day now and the country is on standby ready to celebrate and welcome the new royal family member into the fold.

Last September we learned Prince George and Princess Charlotte would be welcoming a younger sibling in April 2018 - and with just a week left of April, we can expect the Duchess to go into labour any day now.

After the birth, the Duke and Duchess of Cambridge will likely follow tradition and stand on the steps of the Lindo Wing with their newborn as the world sees the youngster for the first time.

To celebrate the impending birth, we’ve rounded up 30 royal baby pictures throughout the decades, from Queen Elizabeth to Princess Charlotte, take a peek by clicking through the gallery above.
