Visitor Policy

I have a large family and extended family plus family friends that I could see coming to visit baby at the hospital or right after we get home. How are you going about telling people your wishes as far as visitors? I’m an introvert and find groups of people overwhelming. I really don’t want a revolving door of visitors. My husband says he’s happy to be gatekeeper but I don’t want to have people show up and be turned away either. I’m also not sure how I’ll actually feel about visitors once baby comes. This is just speculation. Is there a good/tactful way to notify people beforehand of what we’d like as far as visitors? Especially if it’s a large group and you’re not sure who would come? Also we haven’t announced the pregnancy on social media and don’t plan to. Any insight/suggestions are welcome.
