It's A Boy!

Prince William, Kate and their baby boy were spending their first day as a family inside a London hospital, thanking staff for their care but making well-wishers wait for a first glimpse of the royal heir.

As celebratory lights, gun salutes and other tributes were unleashed in Britain and abroad, William thanked staff at St. Mary's Hospital "for the tremendous care the three of us have received."


"We know it has been a very busy period for the hospital and we would like to thank everyone - staff, patients and visitors - for their understanding during this time," he said in a statement.

The couple's Kensington Palace office said Kate, the Duchess of Cambridge, had given birth to the 8 pound, 6 ounce (3.8 kilogram) baby boy at 4:24 p.m. Monday, triggering an impromptu party outside Buckingham Palace and in front of the hospital's private Lindo Wing.

The palace said Tuesday that "mother, son and father are all doing well this morning."

The new family Is expected to remain in the hospital until Tuesday evening or Wednesday morning.

In the meantime the infant's appearance - and his name - remain a royal mystery.
