Parents and experts were swift to respond to the video, with opinion divided on whether the DIY technique is safe to perform.
"As a respiratory therapist, this is the bomb!" one expert wrote.
"Although most kids may not be so co-operative and may require some sort of containment system."
One mum agreed, saying: "Coming from a parent of a stuffy 5-month-old this is definitely worth a try."
However, not everyone was on side with this mother's tip, with one nurse raising concerns for the baby's health.
"This is not a safe practice. It can lead to choking and aspiration which could result in a pneumonia. But what do I know. I'm only a children's nurse," she wrote.
"Looks good and eases child BUT errrrm dry or secondary drowning springs to mind. I wouldn't do it too risky," agreed someone else.
