Issues with mother-in-law

Cindy

So my MIL decided to travel and take the ferry while this covid 19 pandemic is getting worse and I dont want her to come over to my place for 2 weeks after her return because I'm worried she might get covid and pass it on to my 2 year old son who has severe asthma or myself. Being almost 30 weeks pregnant, I want to be a little more careful. My MIL thinks im the worst person in the world because of it and same with my husband. My husband says I'm overexagerating. He always takes his mothers side whenever there is a disagreement on how to raise our son and he despises me for not raising our son the way his mother wants us too. I'm just getting so tired of it all. And I am wondering what you guys think about this situation. Do you think I'm being over paranoid about her isolating from us for 2 weeks when she returns from her trip? Thanks for any advice in advance!
