But still, reports continue to surface that England's future Queen consort has her heart set on one final addition to her young royal family.
"Catherine would like another baby.
"She loves children and is prepared to put herself through another pregnancy even though they have been complicated in the past," a source told the Daily Mail.
Kate suffered with the condition hyperemesis gravidarum during all three of pregnancies, a complication resulting in severe, constant nausea and weight loss.
Speaking to New Idea, another source revealed: "Kate has seen the bond between George and Charlotte and thinks it would be lovely if Louis had a sister closer to his age."
"Kate is doing things her way but William has always supported her and will do anything to make her happy; that is a promise he made before they married."
William and Kate visited the Sussexes' baby boy just over a week after his birth on May 6.
A Kensington Palace rep told People Magazine the private gathering took place at the Duke and Duchess of Sussex' home of Frogmore Cottage in Windsor, with baby Archie's grandfather Prince Charles and step grandma Camilla, Duchess of Cornwall arriving later that evening.
