The Walking Dead star Alanna Masterson posted a photo of 1-year-old daughter Marlowe via Instagram Tuesday.

The new mom, 28, captioned the image while slamming “body shamers” and online “trolls.”

“Dear Instagram trolls, body shamers, and the men and woman who think it’s ok to comment on my weight: I hope that you don’t have children. And if you do, I hope you teach them about kindness and acceptance. I hope they learn that it isn’t ok to make fun of people or call people names. I hope one day YOU learn what it takes to be a parent. A kind, selfless parent. A working parent. A parent that puts themselves in someone else’s shoes. Maybe you can’t get it through your thick fucking skull, but nursing a baby for a year (and pumping in a van between takes, in the dead of summer in Georgia) is a lot of work, determination, and scheduling. So before you decide to make a comment about my chest being “too large” or how “fat” I’ve become, just know that this little girl got the best start to life. I wouldn’t have changed it for a second. I would’ve gladly continued to eat enough calories to produce milk for her little bones to grow,” she captioned the image.

The new mom – who plays zombie fighter Tara Chambler on TWD – went on to identify the online trolls as judgemental bullies.

“Also, grow the fuck up. Your mother should be ashamed for raising such a judgmental bully. I’m sure she knows how “courageous” you must be for trolling and hiding behind your Iphone and computers. P.s. I would LOVE to see any man or woman give birth to a baby, nurse the baby, and then work 17 hour days and NAIL their own stunts. P.s.s. Be kind to each other. We need it now more than ever,” she wrote.

Masterson and her boyfriend, Brick Stowell, welcomed their first child in November 2015.
