I don't live with them but they are just living next door. Most grandparents are like that. Their 安全意識 is very low. Anything from their mouth is right. Things from your mouth is always wrong. Most grandma like to show off their ability. They always think that you are just a new mom and knows nothing about BB. They don't know that most of the new Moms read a lot of books. Grandma just like to use those traditional methods. I do agree that some of those methods are really good but not all of them. You said your 99 is a teacher, my 99 was a teacher too. I totally understanding your feeling. There is no way you can change them. However you can change yourself by thinking that they really love your baby. No need to argue with them because your are always the loser. If they did something wrong, you can have your husband to discuss with them. Since your are a Full time Mom, you still have a lot of time to teach your BB.
