Intervention: Swaddling Method
Description: The preterm infants will be placed in the supine position on a 90 cm2 soft cloth. The upper edge of the cloth will be aligned with the infant's shoulder, with the arms placed close to the body, with the horizontal ends of the cloth folded in the opposite direction to cover the top of the body. The arms will be put into flexion and the body will be covered with a cloth. In order not to limit the movements of all limbs of the preterm infant, attention will be paid to leave a finger space between the infant and the cloth cover and to leave a suitable space for the feet to be comfortable before folding the lower part of the cloth cover forward. In the swaddling method, the baby's head can move freely. The swaddling method will be applied approximately 5-10 minutes before the procedure and will be removed from the infant 5 minutes after the procedure. Because swaddling will increase the body temperature of the infant, the standard temperature of the incubator will be lowered.
