Terrified of baby getting sick

Lori

I was diagnosed with strep last week but have been on antibiotics. One if her brothers has a cough, one has a low grade fever, and the other sounds stuffy. I am terrified the baby will get sick. Terrified mostly of the fever. Anyone in the same boat?

Also, what is the best way to get a temp if needed? I’m scared to do the rectal. Will under the armpit work?

I hope everyone gets healthy soon because my anxiety is through the roof!
