Dealing with mother in law advice on everything

Love my MIL but man she has an opinion on literally everything we do with our newborn. How we hold him, when we feed him, temperature of his bath, how we burp him. My wife gets stressed about it but I've been trying to take it as she just cares. Still sometimes I want to tell her we got this but I know that won't go over well. Anyone else dealing with this? How are you handling it without causing family drama?
