• Olivia Munn shared new photos of her son Malcolm on Instagram
  • She revealed that her hair has been "falling out in clumps postpartum" in the comments
  • Munn and John Mulaney welcomed their first child in November last year

Olivia Munn has revealed another struggle she is facing after becoming a mom.

The 41-year-old actress recently opened up about her experience with postpartum hair loss while giving her followers on Instagram a glimpse of her growing baby boy Malcolm, whom she shares with comedian John Mulaney.

Many of Munn's followers and friends gushed over her son, with one writing in the comments: "I have to hold that baby!!!!"

"I can’t with that cute baby! Just too adorable!" another wrote.

Los Angeles fashion designer Amber Farr, meanwhile, complimented the actress' beach waves, jokingly asking, "Can I just have your hair for one day please?"

The "X-Men: Apocalypse" actress responded, "Ummm it's falling out in clumps postpartum."

"I'll let you have it once I can grow it back and give it to you in better condition," Munn joked.

Munn has been open about the joys and struggles of motherhood since welcoming her son on Nov. 24 last year.

On Friday, she shared a video on Instagram showing a close-up of the actress' hair, which appeared to have milk on it. "When you get your hair blown out and then your baby [face with open mouth vomiting emoji]," she wrote on the video.

Last month, Munn also revealed her typical day as a mother of a 4-month-old baby in several posts on her Instagram Stories.

"Everyone's asleep except me," she said, noting that it was 1:54 a.m. She posed in the mirror for the late-night selfie while wearing a gray Mickey Mouse sweatshirt.

"Been wearing the same sweatshirt for three days (I think, maybe more?) I'm pretty sure that's spit up on my shirt," she said. "I'm so so happy and at the same time I'm struggling (weird to feel both simultaneously yet so grateful to have all the happiness to keep me afloat)."

The "Love Wedding Repeat" actress also revealed on Instagram back in January that she had been struggling with breastfeeding.

According to Munn, she found breastfeeding difficult because she had "low supply" despite having taken "a million vitamins, countless teas, lozenges [and] tinctures" and working with two lactation consultants.

Munn made light of the situation by sharing a photo of her dog resting on her breastfeeding pillow. "At least someone is making good use of my breastfeeding pillow," she wrote in the caption.

Munn and Mulaney first revealed their son in December 2021. "Meet Malcolm Hiệp Mulaney. He has his whole life ahead of him. He hasn't even tried seltzer yet," the comedian joked on Instagram at the time. "I'm very in love with him and his whole deal. Happy Holidays."
