Hi my son is 3 years old he has possible prune belly syndrome but doctors wont confirm it. But he has reaccuring chest infections and is given antibiotics atleast 3 times a year for this should i get this looked into more. I try to leave him as long as possible before taking him to the doctors when he has a chesty cough as i know hes just going to give him more antibiotics.  Due to other problems my son has he has around 6 courses of antibiotics a year.
Holding off for as long as possible is something that is fraught with risk. You may want to hold on for a few days at the most. If there is fever, a yellow phlegm or rapid breathing, holding on even for a few days is dangerous. A nighttime or early morning cough, any pus emanating from one or both ears, pain behind the ear in the bone above the jaw, swelling of the neck glands and difficulty in swallowing should all prompt you to seek help sooner. Antibiotics themselves are not the culprit. Self-administering them, giving them in the wrong way or in the wrong dose, or using the wrong antibiotic, or using them for the wrong duration - those are the culprits.
