It’s hard to say without knowing what you mean by “doing something wrong”. Does “wrong” mean mistreating the children, or does it mean sending the children to a school you don’t like? There’s very little that you can or should bring up with an adult child. You don’t have to stay silent, but if you do speak up, it must be within the context of giving advice- which your child may feel free to disregard. You cannot and should not tell your married kids how to live their lives. You can give them your opinion, phrased respectfully, and with full acknowledgment that they may ignore it. It’s hard to hear, but it’s all you can do.
