The youngest member of the Cameron clan has now taken up residence in Downing Street.
David Cameron and his wife Samantha were clearly delighted as they posed with baby Florence Rose Endellion, who was born unexpectedly early on the family's annual holiday in Cornwall.
As she cradled her precious bundle – now ten days old – the Prime Minister's wife glowed with pride.
Radiant Sam, 39, also looked to be recovering from the birth – which was by caesarean section.
Florence, their fourth child, will share her new quarters with siblings, Nancy and Arthur.
Sadly, the Camerons' eldest child Ivan died in 2009, having been born with a rare combination of cerebral palsy and severe epilepsy.
