AITA for telling SIL she will never see my kids again (over cough syrup)?
What began as a fun long weekend for the OP’s sons, ages 6 and 11, at their SIL’s house for her daughter’s birthday and Memorial Day celebration turned into a parental nightmare. Upon picking up their children, the OP discovered their SIL had given both boys a full cap (30ml) of adult-strength Delsym PM cough syrup, despite knowing the family’s strict no-cough-syrup stance, especially critical for their youngest with asthma. The excessive dose, four times the recommended children’s amount, left the boys unusually asleep at 9 a.m., raising alarms.
The OP’s fury erupted when the SIL showed no remorse, dismissing their concerns with claims the boys were “fine.” Declaring that their SIL would never see their kids again, the OP left with their children, prioritizing their safety over family ties. This story delves into the betrayal of trust, the dangers of unauthorized medication, and the fierce instinct to protect one’s children in the face of reckless family decisions.

The OP’s decision to ban their SIL from seeing their children was a justified response to a serious breach of trust and safety. Administering a 30ml dose of adult-strength Delsym PM, containing acetaminophen, dextromethorphan, and a sedative, to a 6-year-old with asthma and an 11-year-old, without parental consent, was not only reckless but potentially life-threatening. The dose, four times the appropriate amount for a child’s Tylenol, risked severe side effects like liver damage or respiratory issues, especially given the asthma warning on cough syrup labels. The SIL’s prior knowledge of the OP’s no-cough-syrup stance, reinforced by their mother’s medical advice against cough suppressants, makes her actions a deliberate violation.
This incident underscores the sacred boundary of parental authority over children’s medical care. The SIL’s failure to notify the OP during check-in calls, despite having phone service, suggests either negligence or intentional overmedication to manage the children’s behavior, as Reddit speculated. Her lack of remorse, dismissing the OP’s outrage with “they’re fine,” further erodes trust, indicating a disregard for the boys’ safety. The OP’s immediate action to remove the children and sever contact was a protective instinct driven by the gravity of the risk, particularly for their asthmatic son.
The broader issue here is the danger of unauthorized medical decisions in caregiving. Cough suppressants, especially at excessive doses, can worsen respiratory conditions like asthma by preventing phlegm clearance, potentially leading to complications like pneumonia, as the OP’s mother warned. The SIL’s history of arguing for liberal medication use, contrasted with the OP’s cautious approach, highlights a fundamental clash in parenting values, making future trust nearly impossible. Dr. Barbara Sarnoff, a pediatric safety expert, emphasizes that “no one should administer medication to a child without explicit parental consent, especially not adult formulations.” The OP’s ban, while emotionally charged, prioritizes their children’s well-being over family harmony.
To move forward, the OP should have their sons evaluated by a doctor to ensure no lingering effects, like acetaminophen-related liver stress, and document the incident for potential legal or family mediation purposes. For others facing similar breaches, clear communication of medical boundaries and swift action to protect children are critical. The OP’s reaction was not an overreach but a necessary stand to safeguard their sons from a reckless caregiver.
Here’s the input from the Reddit crowd:
Reddit users overwhelmingly supported the OP, labeling them NTA for banning their SIL after she dangerously overmedicated their children. They condemned the SIL’s actions as reckless, suspecting she used the cough syrup to sedate the boys rather than treat a cough, especially given the excessive adult-strength dose and lack of parental consent.
Users urged the OP to have their sons checked by a doctor for potential health risks, like liver damage from acetaminophen overdose, and praised their firm stance. They viewed the SIL’s lack of remorse and dismissive attitude as proof of her untrustworthiness, affirming the OP’s decision to cut contact as a necessary protection for their children.





















The OP’s ban on their SIL after she recklessly gave their sons adult-strength cough syrup was a fierce defense of their children’s safety, shattering family trust.
