Olivia Munn/Instagram Olivia Munn Shares Sweet Photo of John Mulaney and Their Newborn Son Malcolm Hiệp: 'Smooshiest Smoosh' A source previously confirmed to PEOPLE that Malcolm was born on Nov. 24. Late last month, Munn and Mulaney, 39, introduced the world to their baby boy with a set of sweet photographs shared on Instagram. "My Golden Ox baby. Malcolm Hiệp Mulaney. Happy Holidays," Munn captioned her post, which showed her little guy bundled up in a blanket with a light blue cap atop his head. Sharing a similar photograph as Munn, Mulaney wrote alongside his own snap: "Meet Malcolm Hiệp Mulaney." "He has his whole life ahead of him. He hasn't even tried seltzer yet," he added. "I'm very in love with him and his whole deal. Happy Holidays." Olivia Munn/Instagram Since welcoming their baby boy, Munn has opened up about her adjustment to motherhood, revealing on Wednesday that she was having a tough time breastfeeding Malcolm, in part because she was having trouble producing enough milk. "Any other moms takin alll the supplements and teas and tinctures yet barely make milk?" she asked her Instagram followers, alongside a photo of all the products she was trying and a poll letting viewers choose between "Y! Lactating is hard" and "Got lucky. Got milk." (As of Thursday morning, the vote split is 66% to 34%, respectively.) In a follow-up selfie of her looking exasperated, Munn wrote, "8 weeks in and I've taken a million vitamins, countless teas, lozenges, tinctures and worked with two lactation consultants. Breastfeeding. Is. Hard." She also shared a cute snapshot of her dog lounging on her breastfeeding pillow ("At least someone is making good use of" it, she quipped) and added, "[Side note: Breastfeeding is soooo hard, especially if you have low supply.]"
