Husband COVID positive

hi mummies, need advice. my husband just tested positive. my baby is only a week old, i'm worried for him. my husband felt unwell couple days back but only positive on 3rd day. he is isolating inside the other room but i feel it's not sufficient. is it possible for him to check in at facility, or can he isolate at his parents' plc instead? i'm considering going to my parents' for the time being, but also concerned i might be positive later and spread to them. appreciate your thoughts!
