AITAH for refusing to give up my approved time off to a coworker because she says her situation matters more than mine

I work at a small company where time off requests go through a shared calendar and its basically first come first served. Back in the beginning of the year I put in for a week off in the fall. My wife and I have been planning a trip for our anniversary. Flights are booked the rental is paid for and we coordinated with another couple whos coming with us. Everything has been locked in for months.

Last week a coworker came up to me and asked if I could move my week. She said she just realized her kids have a school break that same week and she needs to be home with them because she doesnt have childcare lined up. She said she forgot to check the school calendar when she was doing her requests at the beginning of the year.

I told her I cant. I said I already have nonrefundable flights and the whole trip is planned around that specific week. I wasnt rude about it I just said sorry I wish I could help but this has been set for months.

She got visibly upset and said it must be nice to not have to worry about kids and that people without children dont understand how impossible it is to juggle everything. She said parents should get priority for school breaks because its not like I NEED that specific week I just want it.

That part stung honestly. Like my anniversary trip with my wife is somehow less valid because we dont have kids. Our plans dont matter because theyre not about children.

I feel bad for her situation I really do. But I also feel like if I give this up it sets a precedent that my time is less important because of my life choices. And thats not something Im willing to accept.
