Annie Peguero, a personal trainer and nutrition specialist from Virginia shared a Facebook live video that has been viewed more than 12,000 times explaining what happened on 24 April.
Peguero held back tears in the video and said: "I so love going to church there but I'll never step foot in that church again'.
She was shocked when workers of Summit Church in Springfield interrupted her as she nursed her daughter and asked her to cover up or move to their baby room.
"Right away, the church workers started kind of freaking out and like waving their hands round.
"They were like 'Here, let me get you a cover' and I'm like, no that's ok and they're like 'no, here's a cover'," Peguero detailed in the video.
Peguero said she left her daughter at the baby room but brought her back to the church service when she received a text saying she was needed in the baby room because her daughter was crying.
She was interrupted again when she tried to breast-feed in the service.
"Right away, a woman came over to me and was like 'We have a really nice baby room, let's go to the baby room'," Peguero said.
The woman explained she asked Peguero to leave her seat because the church streams the service live and she wouldn't want to have people see her breastfeeding.
Peguero, who regularly shares videos of herself breastfeeding online, decided to find out if it was a church rule to not allow women to breast-feed without covering up or during church services.
She claims the Pastor's wife said the policy was in place because 'we don't want to make a man feel uncomfortable'.
Women in Virginia are allowed to breastfeed anywhere they have a legal right to be, due to a law passed in 2015.
Peguero encouraged people to share the video to "bring awareness to breastfeeding and to help normalise breastfeeding and to help women feel comfortable about breastfeeding wherever they want."
