Association between sucking performance in preterm infants and developmental outcome at 2 and 5 years of age

Are sucking skills in a specific period (in weeks post menstrual age, PMA) associated with an abnormal development at age 2? Do preterm infants with abnormal sucking patterns in the early post term period differ in motor skills at age 5 from preterm infants with normal sucking patterns in the same early post term period?
