Will and Kate thank every baby well-wisher with a card

The front of the card features an image, similar to this one, of the royals leaving St. Mary’s hospital after the birth of Prince George.

Prince William and Duchess Kate have sent thank you cards to all the well-wishers who congratulated them on the birth of Prince George, Kensington Palace told

The back of the card reads: “Their Royal Highnesses have been overwhelmed by all the wonderful messages they have received and send you their warmest thanks and best wishes.”

On the front of the card, the happy couple are pictured with their newborn baby in front of the Lindo Wing of St. Mary’s Hospital.

In the photograph, Duchess Kate is wearing a cornflower blue dress with white polka dots by Jenny Packham, William is wearing a collared shirt in the same colors, and Prince George is snuggled up in a bird-print blanket by Aden and Anais.

Although thousands of photographs were taken of the royals leaving the London hospital, Kensington Palace said that the image used on the thank you cards was unique — from “a slightly different angle” — and was only for those who had written to the new parents.

The un-signed, postcard-style notes were sent to everyone who included their address in their letter of congratulation.

“The Duke and Duchess of Cambridge are very grateful for the support and goodwill being expressed at this happy time and wanted to acknowledge the letters and gifts they have received,” said the spokesperson for Kensington Palace.

Back in February, William and Kate thanked the public for congratulations on their pregnancy. That card featured Kate in another dress by Jenny Packham.

“Whenever people write to members of the royal family, they make every effort to write back — that is not unique to the Duke and Duchess of Cambridge, but the whole royal family,” the spokesperson said.
