Be cool. Watch him for early signs of infection . All children exposed may not be suffering from disease and in small children it is mostly mild.

You need to seperate him from you but there should be someone who take care of him. Covid in children is not much as danger as like in adults. But childrens are known to spread infection in adults All members should wear mask You can feed him.. you have to wear mask Hand wash Hygiene Monitor his activity, oral intake, urine output.

Give him all normal diet .he may get mild fever ,cough ,cold but all can be prevented with proper  care Can start him some multivitamins  like visyneral z drops 1 ml once daily if not taking.

Hi. Nothing to worry. Wear a Mask at home too. Maintain proper hygiene. Watch for symptoms in the child like fever/cough/cold/loose stool. If any consult a nearby paediatrician immediately
