I feel pressured from my in laws on how to raise my son

I am asian, I just wanna tell that in advance and my husband is American.

I don’t like my inlaws. I really don’t due to how they are (drug addict, perfectionist, vegan advocators, doctorate degrees gratuates, etc) but my husband is semi aware of that. They also criticized each others parenting even before my son was born. And they are totally opposite of my family back to my country. When my MIL helped us for the first 2 months of my postpartum, she was telling me things on what should I do to my son (languages pretty much)

Today, my Brother in Law called my husband and asking what do we feed to my son. (He is one of the vegans in their family)

When in laws calls my husband I don’t jump on their conversation as we are all not close to each other.

Earlier months after my son was born, my SIL called my husband asking if I am still nursing and ditch the formula.

It kinda bothers me that they are expecting already what my son should be like. Or maybe it’s just my mentality. My family and culture is not perfect but I can tell that I will choose my culture more than theirs.

I wanna raise my son my way and I don’t know how to tell that or show that to them without being rude or saying a word when conversations comes up.
