Kate Middleton kept a special commitment to Princess Charlotte when she was recovering from cancer.
The Princess of Wales allegedly felt guilty for not spending as much time with her children as she would want owing to the tiredness induced by her sickness.
Kate is a regular at Wimbledon and is scheduled to participate in the Royal Box again this year.
Princess Charlotte had a memorable experience last year as she made her debut at the legendary event. Kate had promised to take her daughter to the finals as a special gift.
Ingrid Seward, a royal biographer, told The Sun that Kate felt bad about not being able to spend as much time with the children as she would have wanted due to weariness from her treatment.
During the event, body language expert Judi James lauded little Princess Charlotte, describing her as Kate's 'wing-girl.'
According to The Mirror, Charlotte is still exhibiting symptoms of being her mother's winggirl. She is now old enough to walk freely behind or behind her mother, with Kate simply giving her a little, loving touch on the back to pull her forward for handshakes, writes Gloucestershire Live.
Wimbledon began on Monday and will continue until Sunday, July 13.
