Babies grow up, change … and start looking like another one of your kids, according to Kim Kardashian posted an adorable video of her son Psalm West trying to get a few words out (not yet, little one!) and it turns out the KUWTK star thinks her youngest is starting to look more like one of her kids than the other.

“My baby Psalm is getting so big,” the 38-year-old captioned the cute clip of the 4-month-old. “He started off looking like Chicago but now looks like Saint’s twin!”

When the fourth Kardashian-West baby was born back in May, nearly everyone remarked how much their second boy looked just like his older sister Chicago West. This time around, fans and followers certainly flocked to the comments section to gush over how the baby boy has taken on the spitting image of his older brother, Saint West.

“They are so similar! He’s beautiful,” one fan commented, while another chimed in with, “I was going to say he literally looks like a mini Saint!!!!” Plus, another user couldn’t help but congratulate Kim and her husband, Kanye West, on their seriously stellar baby-making capabilities. “OMG YOU AND YE HAVE THE PERFECT GENES,” they wrote on the post.

In addition to showing off her sweet boy’s resemblance to his older siblings, the proud mama couldn’t help but highlight a special moment where her youngest was trying his darnedest to speak!

“Hi cutie,” she said to him, rubbing his little belly. “Look at my baby. Hi cutie! Hi, Psalm.” The tiny tot seemed like he was dying to say a few word, which his mama noticed. “You wanna talk so badly!” she laughed happily as he flailed around a little bit, his eyes huge and eager.

Back in May, an insider dished exclusively to Life & Style about how thrilled the family was when Psalm was born. “Kim and Kanye feel like their family is complete. Kim used her last embryo with Psalm, and four kids is enough for them to handle!” the source revealed. But despite all the joy, it was a bit of a slow start for Psalm’s big sis.

“Chicago didn’t really understand that she was going to have another brother until the baby was born,” a separate source revealed. “There were some jealousy issues to begin with — she’s used to being the youngest and her parents doting on her, but she’s fine now and is adjusting well.”

Considering the cute IG pics we’ve seen of the baby and his siblings, we think things are going pretty well in the Kardashian-West house.
