Prince William and Catherine, Duchess Of Cambridge have thanked hospital staff for the "tremendous care" they have received following the birth of their baby boy on Monday (22Jul13). The royal couple welcomed a son at the Lindo Wing of St. Mary’s Hospital in London and the new parents are grateful for the help from medical staff. A statement issued on Tuesday (23Jul13) reads: “We would like to thank the staff at the Lindo Wing and the whole 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.” Prince William's uncle, Charles Spencer, has added his congratulations to the many well wishes already received. He tells People.com in a statement, "Such lovely news." Spencer also recalled memories of his nephew's birth 31 years ago, when he was an 18-year-old student. He continues, "The teacher rushed into my bedroom to tell me the good news, a bottle of champagne in his hands. Now, 31 years on... we're celebrating this family addition with just as much happiness." The Duchess' parents, Carole and Michael Middleton, were the first official visitors to see the new baby on Tuesday.
