Grandma wont stop mom shaming me.

Some background, my 2yo has a condition that effects his eyes and brain, we don't know the full extent of how much it'll effect him and his development but we learn more over time as he gets older. Anyway, my grandma literally gets mad at me for every medical decision I need to make for my son. Hes fully vaccinated and she threw a fit about that, he gets his flu shot every year and she always freaks out at me about how bad it is for him. He needs eye drops to help strengthen his one eye because he is partially blind and she thinks that I'm terrible for subjecting him to that everyday for months telling me its too traumatic for him. He saw an ENT doctor today because of a speech delay and they told me he should have tubes put in his ears and have his adenoids removed. I was talking with my dad about it, my grandma was over at his house and she cut me off mid sentence and told me I can't let them do that to him and that its just a money grab. She said he needs his adenoids they're useful and there for a reason and I can't let them remove them. She's even told me I take him to too many doctors and that I shouldn't trust most of what they say. She said Im not being a good advocate for him for always listening to his doctors. Shes driving me completely nuts, she has never listened to me about how I want to parent my son. I've switched his doctors before when I haven't felt satisfied with their level of care so Im completely capable of speaking up for him. I honestly just needed to rant because Im SO sick of this woman. Shes not even old and senile, she just turned 60 so its like WHY ARE YOU LIKE THIS 🙃
