Hello I have gone through your complaints. Your child is having continuously viral infection. If the cold
are not associated with fever
then there is no need to worry about. As you have used adequately anti cold preparations and antibiotics, then next best step what you can take is a flu vaccine
. The most common cause for cold is influenza
virus. A vaxigrip vaccine is available against influenza. A pediatric dose of 0.25ml will be given. Proper hygienic condition is to be maintained. The other uncommon thing which has to be ruled out is any aspiration of foreign body. Take the opinion of your doctor.
Thank you. Good day
