Princess Kate: She missed this family celebration after being discharged from hospital. Princess Kate secretly sneaks out of the luxury clinic through the back exit.

Carole Middleton celebrates her birthday shortly after Princess Kate's discharge from hospital Easter Sunday falls on March 31st in 2024 - so Princess Kate would have around two months to fully recover from her operation. However, this also means that Kate may not be fit enough to celebrate her mother's birthday without her eldest daughter after Kate's operation.
