Any advice on overbearing parents ?

Recently asked my family to wash their hands before holding baby, don’t bite her nails with ur mouth, there’s no reason to burp baby with a stern or hard pat (whacking), etc. times

Have changed and the things that my parents did with my siblings and I, I don’t want them to do with my child. They are refusing and saying they know best. They have no boundaries and respect for my wishes. It sucks. Anyone have experience with getting ur parents to do what u want with ur kid? So much has changed, especially health wise and research. I jus wish they’d respect my wishes.
