The patients will be enrolled into the study only after an informed written consent has been obtained from either of the parent/ caregiver. 2 minutes prior to procedure, 1 ml of the solution marked with patients's serial number will be administered orally to the patient by a nurse using the syringe. The procedure would involve putting a 5-6 Fr. OGT in the neonate which will be done by a group of 8-10 nurses who have been specially trained in this procedure. This insertion of OGT will be done 2 min post administration of test solution by a nurse who will be blinded to the contents of the solution.
