Would you choose to deliver alone?

Okay, so, I’m 38 weeks pregnant and have an almost 2 year old. My mother in law is who we have designated to come over and watch our daughter while we are at the hospital. I knew that with everything going on that there was a chance that any one of us could become exposed to the virus. My husband and I have been working from home and isolating for weeks now. I didn’t expect my mother in law to do the same, but I know she told us that she was limiting contact with others. Today she texts us to let us know that she’s having cold symptoms. She states that she’s not sick, mentions potentially being allergies, and that kind of thing. It became a little downplayed as my husband texted back. I was already a little on edge about having someone come into our home and potentially bringing the virus with them, so needless to say I’m pretty anxious with the idea of her still coming over and watching our daughter. Am I overreacting? What would you guys do? I don’t necessarily want to deliver alone, but that seems selfish if it means potentially infecting our household. Am a bit stuck, advice please! 💕
