How to politely tell people NO?

S 🌻 • Mother of one, engaged to my bestie of 10 years 💕

So when I have the baby I would like to spend the first week afterwards together, just my partner and I getting to know our little girl and getting used to life post bump. I know a lot of people are going to want to come to our home and see her straight away (my partner has a pretty big family that we aren’t very close with and can be quite pushy). I want to tell them before hand that within that first week we don’t want any visitors, but I don’t know how to say it without sounding rude. That’s not my intention, I’ve just had such a difficult pregnancy I feel like we’ll need that time alone together to adjust to everything afterwards. Advise?
