And there's a reason why they've chosen to wait until July, as Prince George will have just finished school, as will Princess Charlotte, meaning they'll all be able to attend the special day as the whole family.
Royal children are usually given six godparents, and they do not have to be members of the royal family. Other people in the running include William's cousins, Peter Phillips, Princess Beatrice, Princess Eugenie or Lady Louise Mountbatten-Windsor, and his beloved former nanny Tiggy Pettifier - previously Tiggy Legge-Bourke.
George, who turns five later this month, was also christened in the Chapel Royal. The intricate, cream-coloured lace gown is a replica of the one worn by Queen Victoria and Prince Albert's eldest daughter, Victoria, during her baptism.
The prince, who is 11 weeks old and fifth in line to the throne, will be baptised in the Chapel Royal at St James's Palace in front of close members of the royal family.
The small, intimate ceremony will mark the first time that Prince William and Kate Middleton will officially debut their "party of 5" (as Ayesha Curry puts it).
Kate Middleton and Prince William have announced all the details surrounding their third child's christening, from the date to the location.
His father said he had "thrice the worry now" when he left hospital with Kate to take the infant home to Kensington Palace.
