Why it worked
The video uses relatable parenting humor and a creative, unexpected solution (using a tablet as a pacifier) to capture attention. The visual gag of the father struggling with the bottles and then the baby's reaction to the tablet is inherently shareable.
Summary
A father attempts to feed his hungry baby by holding two baby bottles, but struggles to manage both. He then uses a tablet displaying his wife's face as a makeshift pacifier for the baby, before going outside to ask a neighbor for milk.
