Another shared: "You do realize many woman pump their breastmilk and feed their babies breast milk via bottle? Also, I love how some people think something so personal as breastfeeding is any of their business."
And another wrote: "All I see is a proud papa sharing his family, a mom feeding her son and a grandma doing what they do best ❤️ there's a lot of love in this pic."
This isn't the first time Teigen has been shamed for her nursing decisions. In July, when Teigen shared a photo nursing Miles (and Luna's baby doll), one Twitter user wrote: “Christ in a hand basket. Menstruating, childbirth and sex are natural, too, but that doesn’t mean I want to see pics of it and/or celebrities like @chrissyteigen taking a bath or nursing. We get it."
