When you leave your newborn in someone else's care, you hope that person will do whatever is necessary to comfort your baby while you are away.
However one grandma may have taken things a little too far and now her daughter-in-law does not trust her to look after her grandson again.
The upset mum posted on Reddit explaining her mother-in-law was looking after her two-month-old baby while she returned to work.
"It's very kind of her to do this for our family and I appreciate it immensely," the woman wrote in the post, saying her baby is breastfed and she pumps so he has milk during the day.
They family had been happy with how the baby-sitting was going, until the woman checked the baby monitor app when she was at work and was horrified with what she saw.
"When I looked at the camera, MIL was holding him and she had her shirt up and he was latched onto her breast," the appalled mum wrote.
"I was shocked and horrified. I called her right away and she didn't answer, so I had to sit there and watch her attempt to breastfeed my baby.
"He was latched on, but obviously not getting any milk as my mother in law is not lactating."
The woman quickly called her husband, who eventually was able to get in contact with his mother.
"Apparently the baby was crying so hard, and that was the only thing she could think of to calm him down enough to sleep," she said, saying her mother-in-law told her that she breastfed all four of her children and it calmed them down.
"She was mad that I had checked the camera and told him it was an invasion of privacy. I don't want her watching my baby anymore.
"When I told my MIL this, she freaked out and said I was being a b---h and she was just trying to calm the baby down and it wasn't a big deal.
"My husband understands why I'm upset, but wants to give her another chance to watch the baby.
"He also doesn't want to spend the money to get a nanny or do daycare when she can care for our baby for free.
"I'm so upset with her and just completely baffled at why she would do this that I never even want to see her again, let alone have her anywhere near my baby."
Fellow Redditers were very quick to assure the upset mum she was in the right in this situation.
"No normal human tries to breastfeed a child they are entrusted to look after," one person commented. "This is NOT healthy/sane behaviour. I would be concerned that she has other issues..."
"Seriously this is so creepy," added another. "Like breastfeeding is the ONLY thing she could think of to calm the baby down? Not a bottle? Nap time?"
