I got the "letter of shame" last year. DD missed 9 days, and they wanted doctors notes for every missed day. I emailed the attendance office and let them know I would not be taking her to the doctor to be exposed to other germs every time she was out.
Last year was tough for her, because we moved districts over the summer, then she missed the first week due to COVID. She was dxed with ADHD, and it took a few months for us to figure out that her "stomach pains" were related to that, and not actual illness.
I tried to avoid traveling on school days this year, but then the youngest got cancer, which led us to reschedule our spring break Disney trip. So, I'll send a note to the kids' schools to inform them that the kids will be out for vacation in early December. I will not lie. If someone pursues my kids' absences, then I will give them the whole story. The truancy policy is supposed to catch neglect cases. Once they see that my kids are perfectly "normal" neurotic little messes, they'll move on.
I will not lie. I'm bad at it anyway.
Probably, it won't even hit their radars, because they don't throw up a red flag until 5 unexcused absence, and parents can excuse 5 of the first 10. Our trip is close to the end of the semester, so we'll probably get an obligatory "letter of shame" for each of them, but nobody will actually care.
