They are indeed anaerobic bacteria and thrive in low-acid, oxygen
environments---precisely the conditions presented by improperly
preserved high pH foods. The commonly known danger is that the
bacteria grow and produce the botulism toxin in the food, which would
poison anyone regardless of age.
Infants face an additional botulinum-related risk from consuming
foods contaminated with the spores. The spores can survive transit
through an infant's relatively low-acid stomach. Once in the gut,
they can start growing and producing toxin.
Here (in the USA) clostridium warnings are given for infants under 12
months; for example, parents are advised to avoid giving babies honey
before their first birthday. Four-month-olds are probably more
vulnerable than 6-month-olds, but the risk is still there for older
babies; 95% of infant botulism cases occur in babies 6 months or younger.
