Newborn and Covid

Hi everyone I have a almost 8 week old. His father tested positive for Covid 2 weeks ago and I brought him to my moms because I was terrified I had it too and didn’t wanna give it to him. He was born 6 weeks early. Well I felt fine the whole time and now I have started getting Covid symptoms fever weakness etc. baby is still at my moms and I miss him terribly am I a bad mom for leaving him there? I’m just terrified of him getting it. Also his father has 2 kids as well and they tested positive for Covid a few days ago and he is still bringing them to the house this weekend. I just don’t know what to do I feel like a bad mom because he is at my moms for so long 😭
