Am i being unreasonable..?

So we have our plan in place for who will watch our toddler when I go into labour - my MIL will come to our house which is a huge blessing and help during this time. The issue is she has an underlying health issue which puts her in a risky situation given my husband is emergency services. We dont want her getting exposed if he or I am asymptomatic. Her husband also has a health condition so he won’t be coming to visit or anything, however she could always bring the virus back to him at their house.

The suggestion has come up that she move in with us for a few weeks to help with the baby and also to prevent exposing her husband. Our house is more than large enough to accommodate this, however our in law suite is currently under reno so we would all be in the same living space

I LOVE my MIL, she is honestly a second mom and I love spending time with her, however I am just so not comfortable with having someone move in for a few weeks.. I wouldn’t even let my own mom move in. I like my space and I feel like I won’t be able to be myself or speak to my husband candidly or just have my own time in this situation, even though the help would be lovely, and I’m getting pushback from my husband. I said I would rather not have help than have anyone move in.

Am I being unreasonable..? Please be honest. I’m just a very private person and if I want to sit on my couch and cry because I’m having a hard day dealing with two under two, I want to be able to do that by myself you know??
