As a new parent you will get plenty advice, you should take it all will a grain of salt. Most advice is based on personal experience, anecdotes, or old wives tales. What’s clear, even after having only one child is that each child is unique, each family is unique, and therefore there are not formulas or playbooks or sometimes even rough guidelines for how to parent. Even the scientific / pedatric recommendations can evolve and change between generations. Significantly, my parents generation was encouraged to have infants sleep on their stomachs to prevent SIDS. This turns out to be the exact opposite of the current medical consensus (back sleeping) that changed in 80s and 90s. It is important to follow some basic, common sense ideas, and then find the parenting framework that works for you, your baby and family. This is why I personally liked Cribsheet: A Data-Driven Guide to Better, More Relaxed Parenting, from Birth to Preschool because the author acknowledges the shakiness of the data and encourages a pragmatic approach to parenting1.
