Hailey Bieber calls son Jack her 'personal snack machine' in adorable new video

Hailey Bieber has delighted her followers with a candid look into her new life as a mum, sharing a short video of a playful moment with her son, Jack. The 29-year-old model, dressed casually in a white t-shirt with a mint-green earphone visible, posted the clip to her Instagram with the humorous caption, "personal snack machine."

In the intimate video, Bieber can be seen relaxing in what appears to be a fluffy, white sherpa-style chair. Baby Jack, who is sitting on her lap in a light-coloured, striped onesie, repeatedly reaches up to put his tiny hand into his mother's open mouth. The Rhode founder plays along, looking up with an amused expression as she gently closes her mouth around his fingers before breaking into a wide smile and laughing. The sweet interaction quickly drew an outpouring of loving comments from friends and fans. Fellow model Jasmine Tookes wrote, "Omg stop. So sweet," while surfer Kelia Moniz exclaimed, "It’s tooo muchhhhhhh." Other friends like Stassie Karanikolaou and Lauren Perez simply shared heart and crying-laughing emojis to show their affection.

A New Chapter for Bieber

The post offers a rare and personal look into Bieber's life since she and her husband of eight years, Canadian singer Justin Bieber, welcomed their first child, Jack Blues Bieber, in August 2024. For those unversed, the couple married in 2018. While she shares these small glimpses into her family life, Hailey has been careful to maintain her son's privacy by not revealing his face on social media. This latest post follows that pattern, showing only the side of Jack's head and his curious little hands.

This lighthearted family moment comes during a remarkably busy period for the entrepreneur. Her popular skincare brand, Rhode, which she launched in 2022, was recently acquired by e.l.f. Beauty in a landmark deal, reportedly valued at an impressive $1 billion. Alongside managing her brand, she has continued her high-profile modelling work, recently fronting the 2026 summer campaign for Mango and featuring in Alaïa's Summer/Fall 2026 campaign. In a recent interview, Bieber admitted to feeling "stretched" while trying to balance her demanding career with the new challenges of motherhood, making these cherished, simple moments with Jack all the more special for her and her followers.

More Than Just a Cute Video

In addition to the playful clip, the post also included a second, more sentimental image. The grainy, heavily filtered photo, which has a strong green and blue tint, shows the silhouette of a parent leaning down to affectionately nuzzle a baby. The intimate moment is partially obscured by a large pink heart emoji placed over their faces, reinforcing the private and loving nature of the bond.

While the "snack machine" moment is a source of amusement, experts note that babies putting their hands in their mouths is a completely normal and important part of their development. This oral exploration is a key way they learn about their environment and their own bodies. It can also be a method of self-soothing, a response to teething discomfort, or even an early hunger cue. For Hailey Bieber's millions of fans, however, the post was simply a sweet and relatable peek into her new world as a loving mother.
