North West is the spitting image of her mother, Kim Kardashian.

The reality star proved that when she shared a throwback photo of herself on Instagram on Sunday. The photo showed Kardashian, 38, sitting on the beach in a black bathing suit.

"Baby K," she captioned the image.

Kardashian's childhood photo could easily be mistaken for one of West, 5. The eldest of Kardashian's three children often appears on her Instagram account, showing off her model poses and penchant for makeup and fashion.

This isn't the first time Kardashian has proven just how much she and West look alike. In 2014, the Keeping Up With the Kardashians star shared a side-by-side of one of her baby photos and one of West's. The resemblance between them was undeniable.

"ME/NORTH #MiniMe," she wrote at the time.

Kardashian and husband Kanye West have three children: North, Saint, 3, and Chicago, 11 months. She and her beau are considering a fourth child, though Kardashian is admittedly more on the fence about it than her husband.

"My mom kind of prepped me [for what having three kids was like], and it was crazy because when everyone found out that I was having a third, everyone had a crazy story...like, 'Two was great, but three, you are outnumbered. You are exhausted'...Like all of these nightmare stories," she told ET Online. "[Having a brother for Saint] would be nice. It really would, but I'm very full right now."
