Why it worked
The video provides a practical and relatable "hack" for parents dealing with swim lessons, offering a solution to a common problem (preventing car seat messes) in a clear, step-by-step visual format. The humor and "aha!" moment of the solution likely contributed to its shareability.
Summary
The video shows a child being dressed in layers, starting with a swim diaper, then a bathing suit, and finally a regular diaper over the bathing suit. The final step shows the child arriving at swim lessons, implying that the regular diaper is a protective layer for the car seat and that no changing is needed upon arrival.
