Positive for COVID-19

Just looking for advice... husband and I both tested positive for Covid-19. We are waiting for our sons results. Has anyone gone through this? I have been caring for my baby with and N95 mask on and a sterile gown but I am terrified to think that he might have it too. Should his grandmother take him and care for him away from home? Should I keep taking care of him myself? Im really scared and need some advice and support
