It’s no secret the Kardashians go the whole nine yards for their kids’ 𝐛𝐢𝐫𝐭𝐡days.

Take the courtside Lakers tickets Kim Kardashian got her son Saint West last year or the suite they sat in for a Rams football game the year prior.

While fans will have to wait and see what The Kardashians star got her second 𝘤𝘩𝘪𝘭𝘥 for his ninth 𝐛𝐢𝐫𝐭𝐡day Dec. 5, she doesn’t need a major milestone to give him something special.

Consider their mother-son soccer trips that took them to Spain this past August to meet Real Madrid players, kick the ball around with them and attend a match against Real Valladolid.

“It’s pretty nutty that I travel the world for my kids’ interests, Kim said on an August episode of The Tonight Show Starring Jimmy Fallon, “but it’s fun.”In fact, Kim—who shares Saint as well as kids North West, 11, Chicago West, 6, and Psalm West, 5, with ex-husband Kanye West—said her eldest son’s sports interests have shaped the dating prospects he recommends for his mom.“They make lists,” the SKIMS mogul continued about her kids. “Saint wants me to be with any basketball player or soccer player, and I’m like, ‘If you only knew.’”

The elementary school student also enjoys hanging out with his family, and he’s formed a close bond with Aunt Khloe Kardashian’s 2-year-old son Tatum Thompson.

“Saint is the absolute sweetest when it comes to babies, but his connection to Tatum is one that can’t be explained,” the Good American founder—who shares Tatum and 6-year-old daughter True Thompson with ex Tristan Thompson—wrote on Instagram in September. “They were destined to be in one another’s lives!”
