According to Karen Millen (who is, notably, a clothing designer and not a child development expert), breastfeeding beyond six months has no benefit for the child, is selfish, and is a sign of addiction.
You're not allowed to get it right as a mother, are you? Bad if you don't breastfeed but also bad if you breastfeed for too long, apparently.
God knows why Karen Millen was being asked for her opinion on the subject in the first place 🙄
