Kate Middleton shares childhood photo showing Prince Louis as her mini me

On Feb. 4, Kate Middleton shared on Instagram a childhood photo showing herself as a baby with her dad, Michael Middleton, which was taken by her mother, Carole Middleton. Many fans quickly shared a similar thought: That the Princess of Wales and Prince William's youngest son, Prince Louis, 4, bears a striking resemblance to his mom. Check out the post below!

"Louis is your TWIN," one user wrote, while another commented, "I thought this is Louis."

A third user wrote, "Awww this is such a very sweet picture. Louis looks so much like his mum."

Kate, who also shares with William son Prince George, 9, and Princess Charlotte, 7, captioned her post, "'Faces are a baby's best toy.'
