I think they can ask but can't carelessly say it out loud. Kindergarden teachers need to know a bit about the student's family so they can alert the authorities if abuse happened. And the father, I think that he wants everyone to know the mother's unstable so he can rightfully keeps her at home all the time. If she's not unwell, people will def ask questions.

wait what who's physically ill? i think you're the schizophrenic one fr. my point was that she's being portrayed as vaguely mentally ill yet you so confidently diagnose her with schizophrenia as if that's the only mental illness that exists in this universe. idk if my screen is fucked up and I'm missing panels but it never once says schizophrenia and the teacher/ kid at the beginning only say that she's vaguely not well
Why the heck is the teacher talking about one of the parent's medical condition at school? So unprofessional! Kids repeat everything they hear, as a teacher she knows that! Bet you it's going to get around the school and kids are going to start making fun of him. Plus that kid is probably going to ask his parents what schizophrenia is and they are going to ask him where he heard that word. Then the rumor will be spread by the adults too! And after the rumor spreads, he will know it was that kid who started it and he will hurt him. But he is the son of a CEO of a big company. His dad will do something terrible to him for hurting that kid!
