First\u2010year hospitalizations of infants admitted for neonatal care 0\u20136 d after birth (<jats:italic>n<\/jats:italic>=24 583) were tracked, as were hospitalizations of mothers for whom the date of admission lay\u00b11 mo from the date of delivery. Monetary values were assigned to each hospitalization using the Nord\u2010DRG classification system. <jats:italic>Results:<\/jats:italic> On average, preterm infants (GA&lt;37 wk) had first\u2010year lengths of stay roughly four times as long as full\u2010term infants admitted for neonatal care (30 d vs 8 d, <jats:italic>p<\/jats:italic>&lt;0.0001). The average first\u2010year length of stay of the extremely immature infants (GA 22\u201325 wk) was more than six times as long that of infants born at 34\u201336 wk (108 d vs 17 d, <jats:italic>p<\/jats:italic>&lt;0.0001).
