Soothe a newborn: Swaddle , shushing noise, swing, side/stomach position, suck on a binkie. Read The Happiest Baby on the Block by Dr. Harvey Karp (or watch the video.) It' a life-saver.

Work on developing a “no shortcuts” mode. Looking for a faster/easier/bare-minimum option isn’t always bad. People get paid a lot of money for creating efficacy.
