"Infant botulism affects a baby's nervous system and can result in death. Most babies with infant botulism, however, do recover. Signs and symptoms of infant botulism include:
Persistent constipation
Floppy arms, legs and neck
Weak cry due to muscle weakness
Weak sucking and poor feeding
Tired all the time (lethargy)
Difficulty breathing
Botulism spores may also be found in low-acid home-canned foods and corn syrup. For this reason, you should avoid feeding these foods to infants before 12 months of age"
