A man recently turned to social media for advice after discovering troubling behavior from his former mother-in-law toward his daughter. His first wife passed away during childbirth, leaving him heartbroken—as well as his ex-MIL, “Gill,” who had lost her only child. Over time, Gill began treating his daughter as a replacement for her deceased daughter, something the father found uncomfortable but tolerated out of sympathy.

He explained that Gill often introduced the little girl as “my baby” or “my daughter,” and even created a full nursery in her home as if she were raising the child herself. In the hospital, Gill attempted to convince nurses to let her take the baby home, forcing the father to spend hours proving he was the parent.

For two years he focused solely on raising his daughter. When she was three, he met the woman who is now his wife, someone who loves his daughter deeply. When the girl turned six, he and his wife gently explained that her biological mother had passed away and that his wife was her stepmother—something Gill reacted to with anger and resentment.

Now the couple is expecting a baby boy and preparing to move to another state for better job opportunities and childcare options. Gill has fought the decision from the beginning. She even reported them to Child Protective Services, claiming they were neglecting the girl because of the unborn baby—something she knew could give her a chance at gaining custody. Fortunately, neither their current state nor their new one grants grandparents any legal rights.

Despite Gill’s behavior, the father still allowed frequent visits. However, after her most recent stay, his daughter became unusually quiet on the way home. After some gentle questioning, the girl asked if her parents planned to abandon her once the baby arrived. When he reassured her, she admitted that Gill had been telling her for a year that her father and stepmother wouldn’t love her anymore once the baby was born, and that only Gill would care about her. She also said Gill had been encouraging her to call her “mom” but told her not to tell her parents.

People who read the father’s post expressed sympathy and alarm. Many told him that Gill was emotionally manipulating the child and urged him to stop letting her have unsupervised visits. Others encouraged him to seek therapy for his daughter and to cut off contact to protect her. Some readers, including those who have experienced the loss of a child themselves, said Gill’s grief doesn’t excuse her behavior or her disrespect toward the father’s new wife.

Many commenters advised that if any visits happen at all, they should be supervised—ideally by the father himself—before the family moves away. They wished him the best as he works to protect his daughter and keep his family safe.
