Royal fans could not help but comment on the adorable clip.
One user wrote on TikTok: “Prince Louis watching over his big sister [love heart face emojis]” while another one said: “Prince Louis is a good brother.”
A third one added: “Louis be like: Don’t ever touch my sister” while a fourth one commented: “Love Louis what a little character”.
Mia showed up again on Christmas Day when she was pictured holding hands with her younger cousin as they walked together along with the rest of the royals.
Zara and Mike’s children are known to be getting on quite well with Prince William and Princess Kate’s children. But they often get competitive with each other.
Mike has previously said: “Our kids play with their kids in this competition we have.”
Zara agreed and added: “I think our families are fairly competitive.”
