Princess Charlotte's portraits for her 11th birthday were certainly called out as sweet updates from her life, but it wouldn't be wrong to mention that not everyone felt the same way while looking at them.
This includes Prince Harry, who certainly had some emotions stirred up in him.

The Duke of Sussex and his wife stepped back from their royal duties in 2020 and have since relocated to Montecito, where they are raising two kids of their own.
Seeing how old Charlotte is getting continues to be a reminder of the physical and emotional distance from his loved ones. Archie and Lilli claim to be missing out big time on life with the rest of the family, one insider shared, and that is what makes Harry so sad most of the time.

Harry strongly feels his kids are missing out on the extensive family network that the other cousins are enjoying.
Archie was born at Portland Hospital in London, where he spent the early months of his life in the royal fold, including being by his parents' side for a royal tour in Southern Africa. This is right before his parents relocated to the USA.
