Ask HN: How are you using AI with your kids?

Lately I've been thinking a lot about how I want my children to interact with AI, and I realize that there's not much tooling around parental control or behavioral control of the AI. I was thinking, for example, to have my own GPT with some prompt engineering to make sure the LLM doesn't give answers directly and instead acts more as a guide, and also to make it understand who it is talking to. Has any of you done something about it? I assume AI adoption in households is increasing exponentially.
