My son is 1 yr 11 months old and frequently suffers from cough and cold and running nose. I give T-minic syrup and mucolite drop and my paed has suggested to give lactrum powder for 3 months. Is it OK. Should I avoid orange juice during cough and cold? He also has constipation and sometime it bleeds as stool is very hard. He weighs 11.5 kg. Doctor suggested to give dufalac 10 ml for few days and then 5 ml altogether for 1 week. How can he get rid of constipation. I give 10 oz water daily.
