How to Stop a Baby Crying Instantly

Occurred on August 3, 2019 / London, England, UK

Info from Licensor: "My wife and I discovered that our baby instantly falls asleep when you put on a hair dryer or vacuum cleaner. Even though the hairdryer is quite loud it instantly soothes her back to sleep. We keep it on for about three minutes until she is in a deep sleep then turn it off. It is always on a cold air setting and never pointed at the baby."
