[[File:Lyksborg slot 9-7-2005 nr 2.jpg|thumb|Prince Christian's childhood home, [[Glücksburg Castle]] in Schleswig-Holstein, seat of the [[Schleswig-Holstein-Sonderburg-Glücksburg|eponymous ducal branches]] of the [[House of Oldenburg]] (2005).]]
Initially, the young prince grew up with his parents and many brothers and sisters at his maternal grandparents' residence at [[Gottorf Castle]], the habitual seat of the royal governors of the duchies of [[Duchy of Schleswig|Schleswig]] and [[Duchy of Holstein|Holstein]]. However, in 1824, the [[Anna Karoline af Nassau-Saarbrücken|dowager duchess of Glücksburg]], widow of [[Frederick Henry William, Duke of Schleswig-Holstein-Sonderburg-Glücksburg|Frederick Henry William]], the last duke of the [[Schleswig-Holstein-Sonderburg-Glücksburg (elder line)|elder line of the house Schleswig-Holstein-Sønderborg-Glücksburg]], who had himself died in 1779, died. [[Glücksburg Castle]], located a little south of [[Flensburg Fjord]], not far from city of [[Flensburg]], was now empty, and on 6 June 1825, Duke Friedrich Wilhelm was appointed Duke of [[Glücksburg]] by his brother-in-law, [[Frederick VI of Denmark|King Frederick VI of Denmark]]. Duke Friedrich Wilhelm subsequently changed his title to Duke of [[Schleswig-Holstein-Sonderburg-Glücksburg]] and thus founded [[House of Glücksburg|the younger Glücksburg]] line.{{sfn|Bramsen|1992|p=78-82}}

Subsequently, the family moved to [[Glücksburg Castle]], where Prince Christian was [[child raising|raised]] with his siblings under their father's supervision. The Duke wrote to a friend: {{blockquote|I raise my sons with rigor, that these may learn to obey, without, however, failing to make them available to the requirements and demands of the present.{{sfn|Thorsøe|1889|p=523}}}} However, Duke Friedrich Wilhelm died of a cold that had developed into pneumonia at the age of just 46 on 17 February 1831 and, at the Duke's own discretion, scarlet fever, which had previously affected two of his children. His death left the duchess widowed with ten children and no money. Prince Christian was twelve years old when his father died.
