2 year old with a 4 day old new born

Mackenzie

My 2 year old has a very runny nose and been sneezing a lot but no cough and I’m scared out of my mind of my newborn getting it. My newborn came 2 weeks early and I just wanted advice on how to take care of it. Like should I keep them separate one upstairs one down stairs. Family want to see my newborn and when I tell them well my 2 year old is sick and I have a four day old now I’m stressed I rather not have anyone over right now or am I over reacting. My mother in law mad because she hasent aren’t the newborn yet we had plans for today but I told her my son is sick I rather wait because of how stressed and anxiety I have right now.
