MIL bailed on babysitting duties hours before granddaughter's first field trip — when the real reason came out, her daughter-in-law lost it

Navigating relationships with in-laws can be tricky, especially if they seem to have a favorite. A woman who goes by u/Chemical-Winner-3625 shared an incident when she had depended on her mother-in-law (MIL), only to be disappointed. The mother of three asked her MIL to watch her two kids (4 years old and 6 months old) so she could attend an out-of-town field trip with her daughter. The older woman initially agreed but flaked out at the last minute. When the author found out the real reason she had cancelled, she was furious. The May 26, 2026 post received 70 upvotes and 30 comments.

Changed plans at the last minute

The author admitted that her MIL was mostly good, but there were certain things she did that just irked her. Her MIL had agreed to babysit her two kids three weeks ago. All this time, the author and her daughter had been looking forward to spending time together. They hoped for some mommy-and-daughter bonding time. However, their plans flopped at the last minute because the MIL remembered she had "accidentally" booked an appointment the same day.

She informed the author that it "absolutely cannot be changed," emphasis on "cannot." Even though she was heartbroken that she had disappointed her daughter, the author cancelled her trip. What frustrated her was the fact that the MIL would drop everything for her sister-in-law (SIL). Just last week, the MIL rescheduled one of her appointments because the SIL needed to go grocery shopping, a task which was less important than spending time with her daughter on her first out-of-town school trip.

'She needs more help'

The author was about to brush it off when she overheard a phone call between her husband and MIL. She told him, "You know, SIL just has such a hard time with the two kids. She needs more help. I’m going to her house tomorrow so she can take a nap and clean." Upon hearing that, the author was furious. The MIL could not cancel the "important appointment" when the author wanted to spend some time with her daughter, but could cancel now because the SIL needed some rest. 

The author also pointed out the difference between the working hours of her husband and the SIL's boyfriend. Her husband had longer hours, meaning she had to take care of the house and children more, but the MIL seemed far more willing to drop everything for the SIL. It left the author feeling overlooked and unsupported.

Relationships with in-laws

It is no surprise that people often clash with their in-laws due to differing beliefs, values, and expectations. But it becomes worse if one person is neglected. A YouGov survey found that only 39% get along 'very well' with their in-laws, and 3% do not get along with their in-laws at all. Out of the people who get along 'very well' with their in-laws, the majority of them are men (41%) compared to women (37%).

A Newsweek-funded poll found that 21% of Gen Z participants often clash with their in-laws at least twice a month. This is in comparison to 6% of Millennials and 7% of Gen X. While the author did not have a full-on clash with her MIL, their relationship is nowhere near perfect.

'Your husband needs to have a candid talk with her'

People in the comments felt bad for the mother and her children for being treated this way by their MIL/grandmother. u/Infamous-Let4387 suggested, "Can you hire a sitter? It'll be so worth it. I'm sorry your MIL sucks." u/Sea-Cauliflower-8368 also advised the author. They wrote, "Your husband needs to have a candid talk with her about how her behavior was wrong and how she upset your daughter."
