Is it rude

So my SIL wants to come down to see the baby which is fine but I told her I don’t want her to come down while other people are here due to it being overwhelming. Plus she wants to bring her husband and 2 daughters. When my first born was born she brought her daughter who was sick and told me “it was just her teething” not long after my son got that cold and ended up in the hospital. As well her husband randomly messaged me asking how much I weighed. When I told him he said oh your still sexy. Like CREEPY!!! I don’t want her

Coming till I know my husband will be around and honestly when my child has all his shots. I just feel like I’m already getting stressed by her being around. She even was mad because I rather not have my son on her daughters birthday. Told her I’m going to possibly be induced to to medical issues and she was like well good luck with that. 🤷🏼‍♀️ maybe I’m being over dramatic but idk.
