Baby Feeding. He is around 4 years old!

Hi, Iam mother of 3, my last baby is 2 months old, myself & my hubby is diagnosed with covid+ve around 3 days ago, currently we are into isolation and under covid medication, Can I stop breast feeding our should I continue. There are no symptoms of breathing issue, loosing taste, or cold and fever. Sometimes my just born baby girl use to sneeze n cough, little bit worried. Also day time she will sleep for long hours & but during night time she used to be awake, crying n cough. Could you please suggest me on this. Also my second son is complaining of stomach pain from two days n not having proper food, he will eat a small quantity n says my stomach is full. He is around 4 years old Thanks in advance
