First night home question

So we’re due in about 3 weeks if they induce me. And my question is my SIL AND brother want to meet the baby. However my 7 year old nephew is a lot to handle when he doesn’t get his way. And I don’t want a ton of people holding her with covid going around. And on our first night home I don’t want a lot of family over. How do I politely tell them that without them getting mad? She takes a lot of things so seriously. But my nephew would want to hold the baby constantly and if I take him away they will call me rude and yell at me and it’s my baby and I don’t wanna be mean but I just don’t want people over the first night
