Covid Positive Exposed!

Hi! I’m going crazy! My baby just turned 2 months and had shots yesterday! We also found out that we were exposed to at least 8 positive cases of covid! 7 employees at the store we go to for food and my friends husband. She currently has a temp of 99.6 f but not sure if it’s from her shots or if she got Covid! She is completely herself! No crying, diarrhea, she eats normal! I’m just worried! Has anyone ever had their baby Covid positive? What were their symptoms?
