hi, my husband got infected with covid which is now almost 27 days, may be i was also infected but didn't had much symptoms. but my 2 year 10 month son is not eating at all for 10 days now. he is only having water, juice and milk twice. I am not able to make him eat anything. his appetite is fully gone. is it because of covid? and how can I make him eat and bring back his appetite. he don't have any fever...
