If I ask my kid (early elementary) what he learned last school year, I can watch him apparently genuinely trying to think of some examples and not being very successful. If I ask him something I know he learned he’ll gladly say “oh yeah!” and tell me about it.
LLMs aren't humans, humans aren't LLMs. The fact that your kid can't recall what they learned without you reminding them is natural; the fact that the LLM can't recall something without a reprompt is a failure mode.
