Recently I taught a mom to use the Happiest Baby on the Block techniques to calm her 11 week-old son. He was soon a very easy baby to settle, and was sleeping very well. When she tried to explain these new strategies to her high-quality daycare providers, she was brushed off. They have “their ways of doing things”. Why would any caregiver NOT want to hear what a parent has to offer?
Sadly, the oldest reason in the book. It is new to them, and most people, even the most well-intentioned staff, resist anything new. They can rationalize any other reason, but most of the time it boils down to the simple fact that changing how you understand newborn crying, and changing your response when a baby cries or fusses is hard. Even when the parent is telling you what works.
