Many celebrities support breastfeeding in public, and some of them even document it by posting beautiful pictures on Instagram. Some even post older pictures for World Breastfeeding Week, celebrating the special bond between a new mom and her baby.

Take a look at some of the biggest celebrities who breastfeed in public, who aren’t afraid to stand up for their right to nurse their baby naturally whenever he or she feels hungry.

While she hasn’t been photographed by the paparazzi nursing her son in public yet, Olivia Wilde is certainly on her way to become one of the celebrities who breastfeed in public. She was photographed while feeding her son for Glamour magazine’s September 2014 issue. “Breastfeeding is the most natural thing. I don’t know, now it feels like Otis should always be on my breast,” she explained.

The highest paid supermodel in the world is always busy, so she has to multitask! Gisele breastfed both of her children while getting her hair and makeup done for a photoshoot, and she even posted a picture of it on Instagram. “I think there should be a worldwide law, in my opinion, that mothers should breastfeed their babies for six months,” she told Harper’s Bazaar.

Salma Hayek breastfeeding African baby

Mexican born actress Salma Hayek took it a step further than most celebrities who breastfeed in public, by nursing a hungry baby on a trip to Sierra Leone. The malnourished mother couldn’t produce milk, so Hayek stepped in. “If you have milk, you have milk, and if they’re hungry, they’re hungry. I think it’s a beautiful thing, because motherhood is a very strong place for women to connect and understand each other,” she explained.

Pink breastfeeding on photoshoot

Reality star Kourtney K has been photographed nursing in public in Miami, while lounging by the pool. She’s not just one of the celebrities who breastfeed in public, she also supports wet nursing. “One sister should babysit all the kids, so I can go out or vice-versa, and whichever sister is babysitting should just breastfeed all the kids that are there,” Kourtney told Kim while she was pregnant.

A big advocate of public breastfeeding, Selma Blair also seems to be a fan of attachment parenting, continuing to nurse her 2 year old son. “I don’t care who I offend; my baby wants to eat. If I can’t get a cover over me quick enough, so be it,” she told People.

Many celebrities who breastfeed in public believe that attachment parenting is the best way to go, and “The Big Bang Theory” star Mayim Bialik was photographed breastfeeding her 3 year old son on a New York City subway. “A typical night involved no less than four wake-ups and sometimes six (every 2 hours on the clock for 12 hours of bed time was not unusual),” she explained when publishing the image.
