James, Viscount Severn (James Alexander Philip Theo Mountbatten-Windsor; born 17 December 2007), is the younger child and only son of the Earl and Countess of Wessex, and the youngest grandchild of Queen Elizabeth II and the Duke of Edinburgh. At birth, he was eighth in line to succeed his grandmother; he is currently tenth.
Severn was born by caesarean section at 16:20 UTC on 17 December 2007, at Frimley Park Hospital. Prince Edward, who was present for the birth of his second child, remarked that the birth was “a lot calmer than last time” (a reference to the emergency delivery of their first child, Lady Louise), that his wife was “doing very well,” and that his son was “like most babies, rather small, very cute and very cuddly.” The baby and his mother were released from hospital on 20 December, and the following day his names were announced as James Alexander Philip Theo. Severn was admitted to Great Ormond Street Hospital in London on 24 January 2008, with what Buckingham Palace called a “minor allergic reaction.” He was released from the hospital within days.
Severn was baptised on 19 April 2008, in the private chapel of Windsor Castle by the Dean of Windsor David Conner. His christening gown was a newly made replica of the gown originally used by his great-great-great-grand-aunt Victoria, the eldest daughter of Queen Victoria, in 1840. It has been worn for most royal christenings since then, and the original gown has now been preserved
