Am i “controlling my son” or “keeping him away” by doing this?

I’m due any day and have a one year old. My boyfriend’s family’s side is mainly his dad, his aunt, and his grandma. His grandma has been super helpful with taking me to appointments and watching my son while I’m either in the hospital from complications or during appointments. And I feel like the time we’ve spent with her is more than most grand kids see their great grandmas. She at one point would babysit for about an hour and a half to 2 hours at least once every week, and then after the appointment or whatever was over, we’d spend another 2-3 hours with them. Which I felt like was a good amount of time.

So when his grandma told me that she feels like I “keep him away” and “control him”, and that she feels that way with my relationship with my boyfriend too, it automatically annoyed me. So I told her that it hurt my feelings because I thought she liked me and said that I don’t feel like I control my son or my boyfriend whatsoever and asked what she meant. And told her that I actually encourage my boyfriend to spend more time with them (I didn’t tell her this, but he’s actually wanted to cut her off instead)

She said that she’s offered to take him for me to get extra sleep or do other things but that I “refuse” and had no explanation for how I “control” or “keep away” my boyfriend. But I don’t feel like I’m obligated to just hand my son off when I want to spend that time with him before he is a big brother. And while I could see why she might be upset, calling it “controlling” is a major reach. I’ve had family on both sides tell me that she just wants to be able to have a say so on how he is raised and it gives me a weird feeling. She also mentions “having him through the summer” for weeks now and it makes me uncomfortable because I’m not leaving him all summer. He’s my baby to raise.

What would you do??
