Kylie Jenner unfolds the decoration before Stormi turns 5 and prepares for her son’s big first birthday

Kylie Jenner’s daughter, Stormi, will be five years old this Wednesday, February 1.

And ahead of the special day, the 25-year-old makeup mogul filled the girl’s room with lavish decorations, including a colorful balloon ceiling and a gift basket filled with goodies.

The Kylie Cosmetics founder has a lot to celebrate this week as she will celebrate her son Aire’s first birthday on Thursday, February 2.

She shares both children with the ex-boyfriend of rapper Travis Scott, whom she split from before the New Year after dating on and off for five years.

Kylie shared images of her daughter’s decorated room with her 379 million followers on Tuesday afternoon.

An array of pink, purple, green, yellow, and blue balloons with vibrant ribbons hovered over Stormi’s blushing-toned bed.

There was also a large rainbow unicorn balloon mixed in among the sea of ​​colors.

A pink balloon in the shape of the number five was tied to the older Jenner-Webster’s nightstand.

At the foot of Stormi’s bed was a gift basket with a unicorn’s face on the front.

It was wrapped in transparent iridescent tissue paper and tied at the top with a pink satin bow.

Several of the treats peeked over the edge of the basket, including adorable My Little Pony toys and many of Stormi’s favorite candies.

“My baby is 5 tomorrow,” Kylie captioned, followed by several teary-eyed emojis.

In the past, Kylie treated Stormi with extravagant birthday parties.

Her first and second birthdays were honored with a Stormi-themed carnival complete with classic games, carnival rides and prizes personalized with the girl’s likeness.

‘Stormi World’ reportedly cost over $100,000 to put up.

Although Stormi’s third birthday plans were hampered by rainy weather, the billionaire still managed to host a castle-themed event at her Beverly Hills home.

Last year, the lavish celebrations returned in full force when she and her sister Kim Kardashian hosted a joint Barbie and LOL Dolls themed party.

But with her son turning one just one day after Stormi, it’ll be interesting to see how the party plans play out.

Earlier this month, Kylie revealed her baby’s name and face for the first time after nearly a year of waiting.

She discarded Aire’s birth name, ‘Wolf’, just weeks after he was born because she believed it ‘didn’t fit’ his personality.

Kylie made the big reveal by uploading a slideshow of snapshots with Aire, with just her name as the title. Air means Lion of God.

The first snap she shared was an adorable mirror selfie she had taken while holding her 11-month-old son in her arm. Kylie kept things comfortable in an olive green long-sleeved hoodie paired with matching sweatpants.

The star’s brunette locks were easily pushed back from her face and styled into a messy daytime hairstyle.

Her youngest daughter was also wearing a casual Posh Peanut blue shark ensemble as the TV personality got a full look at Aire’s face for the first time.

The Kylie Cosmetics founder held her large smartphone partially in front of her face as she took the selfie in what appeared to be a spacious modern bathroom.

The mother-of-two then shared a cute photo of Aire sitting comfortably on a cream sofa while sporting a sleek black beanie over her curls. She looked up at the photograph, one hand balanced on the edge of a laundry basket.

She also uploaded a snapshot of her hugging her son as he flashed a happy smile on his face. Kylie, who is also the mother of four-year-old Stormi, whom she shares with Travis, added a vintage filter over the loving photo.

The last image she added to the series included a close-up of her almost-year-old son sitting in a high chair with a food stain on his face and bib as warm sunlight streamed in from a nearby window.

She also explained that her son’s unique name is pronounced ‘air’ under a post on a fan account.

Social media users were quick to comment on the big reveal, including her sister, Khloe Kardashian, who wrote: ‘The king! Young King!!!!!!’

Kylie’s mom, Kris, also shared her own thoughts with her daughter and grandson, writing, “I love you Aire Webster,” followed by a red heart emoji.
