"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.) On 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." Olivia Munn.
