Covid 19 panic

Guys I really need your help to not panic. Any other moms children diagnosed with covid? We just came back from the pediatrician and two of my children were just diagnosed with covid. I’m sure they were exposed at their dads house( divorced) and my daughter came back with a fever. I’m scared because of our newborn and also just for them. We decided to have my oldest who wasn’t exposed leave to his aunts house and my newborn is now with my husband at my in laws which is the hardest thing I’ve ever had to do. Any one experience this with their children? Really need some encouraging words right now 😭
