In August, the Princess Diaries actress opened up about her personal experience with nursing her son in an Instagram post written in honor of National Breastfeeding Week. Moore posted several photos of herself nursing Gus. "Breastfeeding is not always smooth sailing (clogged ducts, timing life around feedings, pumping for when I'm at work, etc… ) but nursing this baby boy for the past nearly 6 months has been a beautiful, messy and an oh so rewarding experience I will treasure forever," Moore wrote. "It goes without saying that #fedisbest," she continued, "and I'm grateful to my body and the tremendous support I've had around me (especially in the beginning days and weeks when I had no clue what I was doing) for allowing me this time to nourish my sweet guy." While appearing on an episode of the Informed Pregnancy Podcast in March, Moore told host Dr. Elliot Berlin that she dealt with "newbie nipple soreness and had to build up my tolerance and threshold." "You get calluses on your nipples and then it doesn't hurt as much," she explained at the time, before adding that Gus is a "great feeder" and a "great sleeper."
