Am I wrong for feeling this way?

So my SO is mad because I really don’t want anyone coming to the hospital at least for the first day when I have the baby. I’m a first time mom and I just don’t feel comfortable having a lot of ppl. He wants his mom there and his side of the family and he’s getting mad because I said no. I don’t plan on letting my family be there. Also is it rude for me to tell his family and mine not to post my baby. Because we don’t get on social media so I do not plan on posting her. Should I feel bad?
