18 Sweet Photos Of Kim Kardashian's Son Saint West To Celebrate His 3rd Birthday

It's hard to believe that Kim Kardashian and Kanye West's only son, Saint, turns 3 years old today. On Wednesday, Dec. 5, Mr. Saint West grew up a bit more, and the mom of three adorably celebrated the occasion on Instagram. "I must have done something really special to deserve having you as my son," Kardashian captioned a sweet photo of her little guy. And in honor of his special day, these photos of Kim Kardashian's son Saint are the perfect way to celebrate his birthday and see just how much he has grown up over the years.

Saint might be the middle child — between his sisters, 5-year-old North and 11-month-old Chicago — but his personality always shines in his own unique way. And based on everything people have seen of him and know about him, Saint is super smart and, of course, just adorable. He enjoys going to baseball games with his dad, he's protective of his younger sibling, and even knows how to spell "gargantuan," according to People.

Even Kardashian can't stop talking about her sweet baby (now grown) boy. Kardashian told Ellen DeGeneres in April 2017, during an appearance on The Ellen DeGeneres Show, that Saint takes after her, according to People. "He's my twin," Kardashian said. "He's literally my twin personality. He's so sweet. And he's just such a good boy. Such a good person."

In honor of Kardashian's little twin, these super adorable photos of Saint show just how sweet he is.

His Big Debut

It took two months after Saint's birth for Kardashian to share the first photo of him to Instagram, according to the Daily Dot. The wait was worth it — Saint made his Instagram debut in February 2016 on his late grandfather's birthday.

In a post on her app, Kardashian wrote that she chose that day to share his photo for a special reason, according to the Daily Dot. "I know there is nothing more in the world he would have wanted than to meet his grandchildren. So I wanted to share this pic of Saint with you all."

After that, Kardashian couldn't stop posting photos of Saint — and it's a good thing she did.
