Girls, the son has a cold, the pediatrician listened and said there's phlegm. She prescribed Ambrobene syrup. Did you give it at that age? I just heard that children have trouble clearing phlegm and it stays inside. Dry cough. And a second question: the son has hard stool, they prescribed Dufalac for a month to take. Did it help you? Several pediatricians we visited, so many doctors, so many prescriptions.
