Case Study: Floppy Baby

Case Study:

A 6-month-old infant is brought to the emergency department with a history of poor feeding, lethargy, and floppy limbs. The baby was previously healthy and had been exclusively breastfed. The parents report that the infant’s cry has become weak and the baby seems “floppy” when held.

Physical Examination:

  • The infant is hypotonic (floppy) with decreased muscle tone
  • Weak cry and poor suck reflex
  • Normal vital signs
  • No signs of trauma or infection

What is the possible diagnosis and what would you like to investigate further?

Good question! The differential diagnosis of floppy baby syndrome is wide. The are many causes. We need more history. How long are the symptoms? It seems birth history was normal. Was newborn screen (NBS) normal? Were all
Milestones normal until recently? Any cosanguineous marriage?
Botulism is ruled out as there is no history of honey consumption.
You may be taking us towards Werding Hoffman.
