Which tool can increase comfort for a preterm infant with no history of complications?

Using a developmentally appropriate pacifier can significantly enhance comfort for a preterm infant without a history of complications. Pacifiers can help fulfill the infant's natural urge to suck, which is important for calming and soothing. The act of sucking not only supports comfort but also can stimulate the development of oral motor skills, which is beneficial as the infant matures.

Additionally, the use of a pacifier has been associated with promoting non-nutritive sucking, which can facilitate weight gain and reduce stress during feeding. It's important to ensure that the pacifier is developmentally appropriate, meaning it is designed specifically for the size and age of preterm infants, to avoid any potential issues with safety or feeding.

The other options do offer comfort but fulfill different roles. A warm blanket provides warmth and helps maintain body temperature, while skin-to-skin contact promotes bonding and regulation of vital signs. Soft music can create a calm environment but may not provide the direct comforting interaction that a pacifier does. Each of these elements contributes to comfort in their own way, yet the pacifier stands out as a specific tool for enhancing the comfort related to the infant’s natural reflexes and developmental needs.
