Unsolicited advice from MIL

So ever since I can remember, I never wanted to eat fruits and veggies. My mom fed them to me as a baby but let's be honest, babies will eat whatever their parents feed them if it tastes good then. Tastebuds change and people change. I don't currently eat fruits and veggies and have had an amazingly healthy pregnancy. Baby is due Monday and he's healthy from all the scans. Literally have not had any bad pregnancy symptoms. Well my husband's mom thinks it's ok to tell me not to influence my child to hate fruits and veggies. Like why would I do that? You think I like being so picky? I don't. I wish I could eat a good healthy salad or a side of fruit. But I won't force myself to eat things I don't have a taste for. My son isn't even born yet and she's telling me not to do this to him. No one did this to me! My mom fed me fruits and veggies and baby food that had stuff I didn't like in it. She never told me it was gross, one day I just didn't want to eat that anymore. I just think she thinks since I'm 22 that I won't do what's best for my own kid. I may not know everything but what mom does?!?!? We learn as we go and try and make educated decisions and raise our kids to the best of our ability. Why do people feel the need to not trust my judgement. I wish I could say something and shut them all up but I am not a confrontative person. She also says her bags are packed so she can come to the hospital the entire time I'm there!!! No! My husband even said he would tell her no that she can't come until I am ready. Why do people not respect a new moms boundaries and requests. Should I just tell them straight up what I expect.
