Khloe Kardashian left fans swooning over her two-year-old son Tatum’s latest Halloween look.

The 40-year-old reality star took to her Instagram to share an adorable photo of her little one as he sported a pair of themed pajamas, getting into the festive spirit.

In the photo, Tatum could be seen flashing a smile at the camera while he stood in front of a large white couch.

Khloé’s followers couldn’t believe how tall her little one had grown as one user commented, “He’s already so tall! WOW! Such a doll.”

While another one chimed in, adding, “Wait? Wait!! Why does he look so tall?”

A third questioned in disbelief, “He’s so tall!” A fourth said: “Tatum is so big now and cute.”

However, the little one is following in the footsteps of his parents, with Khloe standing tall at 5’10 while his dad, Tristan Thompson is 6’9.

During an exclusive conversation with her mother Kris Jenner on The Kardashians in 2023, the Good American founder opened up to her about struggling to embrace Tatum as one of her own.

She said at the time, “With True, it took me a couple of days to be like, OK, this is my daughter. With him, it’s taken me months. I love him and I love kids but, I still don’t have that complete bond.”

The mom-of-two, who also shares daughter True with former partner Tristan, welcomed Tatum via surrogate in July 2022.
