My dad gave me the worst advice ever

He told me to just "let the baby cry it out" when our 2-week-old was struggling with gas. Like yeah Dad, let me just ignore my newborn because that's totally the move. Then he got defensive when I said that wasn't happening. Love the guy but he had three kids in the 80s and it shows lol. Anyone else dealing with well-meaning parents who are stuck in their era?
