“TBT 2014 Wonder Woman!” the actress, 42, captioned the pic. “#normalizebreastfeeding.”

The former Charmed star, who has received some backlash for her handful of nursing pictures on Instagram, says she has no plans to stop anytime soon.

“I don't care,” she told ET when asked about the social media haters. “I'm going to keep breastfeeding, maybe even until [Elizabella is] 6!”

The mom of two, who also has a 4-year-old son named Milo, explained the difference between how people act when they see Miley Cyrus’ nipple on camera and when they see her feeding her child.

“Everyone's fine with her nipples being out,” she said. “I think people are more comfortable sexualizing breasts than relating them to what they were made for, which is feeding another human.”
