AITA for kicking my MIL out after she hit my kid?

A 65-year-old mother-in-law moved in with her daughter and son-in-law, claiming she felt unsafe living alone. What began as a temporary arrangement quickly escalated into ongoing conflicts over space, finances, and household responsibilities. In addition, what makes the story more complicated is her refusal to contribute or help, despite her active lifestyle.

Tensions reached a breaking point when she physically struck one of the grandchildren over a minor interruption. The father, protective of his children, packed her belongings and left them on the porch during her absence. Now, with family divided and his wife siding against him, he seeks clarity on whether his actions crossed the line. This incident highlights the challenges of multigenerational living and the limits of tolerance.

Physical discipline crossing into harm demands immediate intervention to protect children. In this case, the mother-in-law’s actions escalated from neglect to violence, striking a child hard enough to cause bruising over a trivial matter. This reflects deeper entitlement issues, where she prioritizes her comfort over family harmony. Opposing views might argue cultural norms in some regions tolerate corporal punishment, yet modern standards condemn any act leaving marks.

What makes the story more complicated is the wife’s alignment with her mother, potentially straining the marriage. The husband faces a choice between unity and child safety, especially in a context like Lebanon where legal recourse is limited. Broader societal shifts show increasing rejection of elder authority when it endangers the young.

As child psychologist Dr. Laura Markham states, “Any hitting teaches children that bigger people have the right to hurt smaller people” (source: Aha! Parenting website). This underscores why eviction, though drastic, prioritizes protection.

In addition, family dynamics often enable such behavior through fear of conflict or gossip, but tolerating abuse risks long-term trauma for the kids.

Here’s what the community had to contribute:

Many users rallied behind the father, stressing child safety above all else.

The father’s decision to evict his mother-in-law stemmed from repeated boundary violations, culminating in physical harm to his child. While most family members supported him, divisions with his wife and some relatives reveal the emotional toll of such conflicts. Ultimately, prioritizing children’s well-being emerged as the core issue, regardless of cultural or logistical challenges.

How far should parents go to shield kids from harmful relatives? What role does spousal support play in resolving in-law disputes, especially in close-knit families?
