N/A Preterm neonate's nutritinal status. Intervention 1: In the first intervention group, non-nutritional sucking stimulation will be performed using a pacifier twice a day in the morning and in the evening while doctor start to feed infant. The intervention will be performed for 10 consecutive days by trained expert. Oral stimulation program contains two forms of oral stimulation. Around and in mouth stimulation will be done by hand for three minutes and it will be continued sucking by use of a pacifier for two minutes. Intervention 2: In the second intervention group, non-nutritional stimulation will be done by use of breast twice a day in the morning and in the evening for 10 consecutive days by trained experts. Before stimulation, breast milk will be fully discharged. Also before stimulation hands will be washed with soap and water and latex gloves will be used. Oral stimulation program contains two forms of oral stimulation. Around and in mouth stimulation will be done by hand for three minutes and it will be continue by sucking breast for two minutes. Before, during and after the stimulation, the infant will be monitored by the investigator and stimulation will stop immediately observing any interruption in breathing, slow heart rate and disruption in the oxygen supply. Intervention 3: In the control group, infants will receive non-specialized head and face stimulation in addition to routine nursing care, as placebo.
