There will be two groups in the study ( group A & group B). The enrolled neonates will be administered either a sterile solution of 24% sucrose or double distilled water orally. These solutions will be prepared under all sterile precautions by the laboratory staff unrelated to the study, and packed in 2 ml sterile syringes further covered with opaque sealed envelopes bearing serially numbered patient codes. The composition of these packets would be decided by a senior consultant in the department of pharmacology who would have the access to the randomization sequence and would be uninvolved in the present study. Fresh solutions will be prepared daily and unused solutions will be discarded at the end of the day to be replaced with identically numbered solutions from the laboratory. All study solutions will be stored in the refrigerator at 2-8 0C until they are used.
