Hello dear! The medicines prescribed by the doctor are alright but i would like you to have a blood culture report done so as to know which antibiotic should be prescribed depending on the sensitivity of the bacteria causing the illness. you should give himsoft diet for atleast 1 week like porriage,wheat or rice cereal,custard,bread soaked in milk,boiled rice with properly cooked and mashed beans/lentils.. A balanced diet which has less spices and fat. Give him boiled water and fresh vegetables and fruits after washing them and peeling them properly. Maintain a goog hygiene. Hope it will help. Wishing your child good health :-)
