Awwww.

Prince Louis was christened in July and at the time, Kensington Palace released a number of official portraits of the little prince, his parents and his siblings. However, since then, they have stayed out of the limelight, enjoying some family time together as Duchess Kate spends her maternity leave with her children. According to reports, little Louis has changed considerably in this time and now we're just mad to see another peek of the adorable little boy.

The Duke and Duchess of Cambridge have released an additional photograph taken following the christening of Prince Louis.

The Duke and Duchess hope that everyone enjoys this lovely photograph of Prince Louis as much as they do. ? @mattporteous pic.twitter.com/Ix9CykzeBx — Kensington Palace (@KensingtonRoyal) July 16, 2018

A royal source spoke to Us Weekly recently and apparently, he's now sporting a full head of hair. CUTE. The insider revealed:

"Louis has changed a lot since the last photos of him. He's still very chubby but he's grown fast and has a lovely head of hair on him".

Apparently, Louis is a dream baby too as the source shared that he is very easygoing.

 "He's very quiet and content, always smiling and happy".

The Duke and Duchess are thought to have found the transition to three children "easy" and haven't required any additional staffing thus far. Charlotte is thought to be besotted with her little brother and has a "great bond" with him, it certainly looks that way in this snap.

The Duke and Duchess of Cambridge are very pleased to share two photographs of Princess Charlotte and Prince Louis, taken by The Duchess at Kensington Palace.

Here's hoping they treat us to another picture of the three dotes soon!
