Visitors after C-section

So I’m having my second c-section in a little less than a month but not only am I having a c-section I am also getting my tubes tied as well so that’s 2 surgeries in 1. Well my grandmother today was talking about bringing my 4 year old son into the hospital and I told her he’s not allowed because of the new rules and she responded with “well rules will be broken” so I sat there and said no they won’t because no one is coming to the hospital to see the baby. She then started to cry and was like what I can’t see her even after she’s born and I said no. When we come home you are more than welcome to come see her but when I am in the hospital I don’t want anyone but myself and my husband there. I think I’m just frustrated with the way she reacted because this is MY child and I don’t owe anyone a thing. I am have major surgery I want time to get back to myself somewhat and to bond with my daughter. I was more annoyed with the comment of breaking rules because that’s disrespectful to other mothers and the hospital staff but I was very nice in the way I told her I’m not allowing visitors and for her to still react that way really made me feel bad but also be upset that what I want can’t be respected.
