This marked Catherine's return to public life after a long and difficult journey, where she spoke openly about her experiences with grace and strength. Although the focus was largely on her health and recovery, it was her warm moments with Prince Louis that resonated with the public. Catherine affectionately called him "Lug" while encouraging him to lead the way as he confidently walked ahead of his siblings and parents.

This endearing term highlights the strong bond they share, adding a personal touch to the public's perception of the Princess' life. Catherine is then seen pushing Louis on a swing, where he excitedly stands up. In another scene, Louis sits next to Catherine and leans into the camera to say “hello.” The charming nickname isn’t new to royal watchers; Catherine first called him “Lug” during a public appearance at an event last May.

She complimented him when he helped push a wheelbarrow and later when they toasted marshmallows. Louis’ affectionate nature and close relationship with his parents likely inspired the playful nickname. He often shows his affection by tugging on Catherine’s hand as she holds her siblings or hugging his father. His adorable gestures have delighted royal fans, as seen in a viral video of him trying to get Catherine’s attention as she sits with Prince George and Princess Charlotte.

One fan commented on how Louis tugs on his mother, showing his affection. In another instance, while playing cards on a picnic blanket, Louis ran up to his father and hugged him, and William warmly returned the hug. Louis's bond with his parents is evident in their public outings, reflecting the deep family bond that Catherine and William cherish.

The nickname "Lug" perfectly captures this sentiment, illustrating Catherine's affectionate view of her son's loving personality. Catherine and William often use sweet nicknames for their children. For example, in a 2019 video at the Chelsea Flower Show, William affectionately called Charlotte "Minion," a term that means small and cute in French. Catherine has also been known to call Charlotte "Lty," while Prince George is known as "Little Grape."
