There is no way botulism bacteria can grow in honey as  it is too acid.
Botulism bacteria grow in low acid media that is why low acid foods like green
beans are pressure canned or pickled with vinegar.
If the spores of bacteria are able to grow in an infants digestive tract that
is another thing entirely.
Unless your dinner is eaten in a glove box the dust in the air will deposit
spores for butulism bacteria on it.
