ELI5: Why is honey dangerous to toddlers and infants?
gpt
Honey often contains botulism spores, growth of botulism is suppressed when there is low water activity (such as in honey), and it's suppressed when the pH is low. It needs to get 125'C to kill the spores. Botulism produces one of the most toxic poisons  known to man when it grows.

The temperature to kill botulism is too high for honey (it would ruin it). For adults this is a non-issue because it doesn't grow in honey, and when you eat it your stomach acid prevents it from growing. Babies don't have a low enough pH in their stomach (not enough stomach acid basically), so botulism can grow in a babies stomach after it mixes with water in their stomach which could be deadly.
