As revealed by HELLO! the couple have just hired a Spanish nanny who studied at Norland College in Bath, Maria Teresa Turrion Borrallo, to care for the little chap during the trip.
The royal parents felt confident enough to leave their baby in her capable hands as they holidayed at a five star resort in the Maldives.
Mothering Sunday will no doubt be spent quietly either in Kensington Palace or more likely at the Middleton family home in Berkshire so the Duchess of Cambridge can congratulate her own mother Carole.
Thoughtful William has probably picked out a gift for his wife. By her own admission Kate is "very well looked after" by her Prince and he is reported to have given her an eternity ring on George's birth.
When the baby heir arrived on July 22 after the most watched pregnancy in history, the couple were euphoric.
"We could not be happier," said the Duke of Cambridge. William and Kate's feelings were shared by the Queen and both families, who were "delighted" by the news said Kensington Palace.
The trappings of tradition such as the birth announcement on an easel on the Palace gates can't obscure the fact that his birth was genuinely joyous family occasion.
Prince Charles released his own statement, saying he was "thrilled" about "this special moment". He practically hasn't stopped beaming since, waxing lyrical about grandparenthood on every occasion.
For the parents the initial period was relatively tough. William admitted he found being an RAF pilot was easier than fatherhood and that George was "a little bit of a rascal" who reminded him of himself and Harry when they were younger.
Meanwhile, Kate, although smiley and warm as ever, understandly showed the effects of lack of sleep.
Fast forward a few months and the Cambridges seem to be settling into a happy routine. The Duke has left the search and rescue service, giving him more time to devote to his family and develop his role as future King.
His relationship with Kate is stronger than ever - as seen when he called her 'Poppet' outside St Mary's Hospital and then at Christmas when the couple held hands at church in a rare public display of affection.
Nor can they stop talking about their darling boy. George is "busy crawling and eating" and has a tooth, they informed Irish Guardsmen over lunch on St Patrick's Day.
In April, the public will have the chance to see just how well the little Prince is doing and how Kate has blossomed as a mother when the most eagerly followed family in the world land in Australia.
