Kylie Jenner's baby Stormi is growing up so fast — here's the latest photo proof

The reality television star welcomed her daughter four months ago already, but has shared few photos of the little one since.

Towards the end of 2017, rumors were running rampant that 20-year-old Kylie Jenner was expecting a baby. Despite her very public life and general activity on social media in everything she does, Jenner refused to confirm or deny the rumors.

On February 1, Jenner welcomed a baby girl, and explained she had wanted to enjoy her pregnancy journey in private.

Now, 4 months later, fans are still only being given small glimpses of the little girl Jenner named Stormi Webster.

On June 3, Jenner took to Instagram to wish her nieces North West and Penelope Disick a happy birthday. The image she shared was of herself and 4-month-old baby Stormi.

"Happy birthday North & P.," she captioned the shot.

In the image, Jenner was carrying her baby girl in a Gucci baby carrier against her chest. The starlet herself is wearing a white shirt and a pair of khaki shorts. Her hair is pulled back neatly.

It is the first time Stormi has appeared on social media since Mother's Day, when her aunt Kourtney Kardashian shared a snapchat story while holding the infant

She even gave Stormi the adorable pink bear ears filter, making her look even cuter than she already does.

Jenner also shared a photo with her daughter to mark Stormi turning 3 months old at the beginning of May. The image featured the mother-daughter duo in matching white outfits on a deck chair.

Jenner simply captioned the post "Angel baby," and the sweet pic raked in almost 9 million likes.

"Cute cute cute cute cute cute cute I love your baby so much," commented Donna Gucci, and Sierra Marrie added: "I want to see more pictures of Stormi!!!"
