[gotcha] LLM generates pediatric medication dosing without verified age and weight

Gate every pediatric dose recommendation on both age and weight. If either is unknown, refuse to output a numeric dose and direct the user to a pediatric formulary or clinician. Apply the correct maximum daily limit for the child's age/weight band and never extrapolate from adult dosing.

Journey Context:
Pediatric dosing is weight-based and non-linear, but LLMs often hallucinate plausible-sounding mg/kg values or apply adult ceilings. The failure mode is silent: a wrong number looks authoritative. Requiring age and weight as hard preconditions, then looking up a verified pediatric reference, removes the model from the dosage calculation entirely. This is safer than asking the model to 'be careful' because it prevents generation when inputs are insufficient.
