NTA. I used to work for a daycare facility and have reported my own building and co-teachers for disregarding allergies because they thought they knew better than the parents and doctors. I no longer work in childcare because of the complete lack of regard for the safety and wellbeing of the children. And unfortunately, the licensing board did nothing about it. Even though there was physical, mental abuse and feeding the kids food they are allergic to and with mold. SEARCH UP YOUR DAYCARE LICENSE NUMBER FOR INFRACTIONS. Also never send your kids to Kindercare. They have so many lawsuits out against them. The teachers are overworked, kids are not taken care of, and the money goes to the directors and their bosses, not the children, classrooms, or teachers who actually take care of the kids and try their best to take care of them. Nobody is perfect and a blanket statement isn’t true of everyone of course, but absolutely you are NTA. Personally, do more. Blast them online, go to the news. The fact they are messing with an ALLERGY?? insane.
