In laws - Not allowing to visit baby immediately once born

I will be giving birth this month (July 2022) and im gg to be a FTM. I am an introvert and im not very good at adapting to change and esp becoming a new mom so i think i will need time to adjust and just find myself, collect my emotions & thoughts etc. What do you guys think about me not allowing MIL to immediately come and visit me & baby? Is it wrong? I have an ok-ok rs with her. (she has only been nicer to me bcs im pregnant, we didnt rlly have a good past). Am i being selfish or evil? This will be her first grandchild btw. My parents think that its not right. #firstbaby #pleasehelp
