I’m going into hibernation with my kids

I’m having a baby shower this weekend. After this I’m not talking to anyone or letting them know what’s happening with me and baby. This has been a tough pregnancy and everyone acts like they know so much. I’m due in December and i really don’t want anyone around me or my kids. I have a 5yo that was a micro preemie and every December he gets the worst cold no matter if he has flu shot or not. My new baby i just don’t wanna deal with anyone. I wanna spend all my time with him. I wasn’t able to with my first. I’m not sure if i should warn certain people or if i should just block everyone and not say anything.
