In pediatrics, a 30-week gestation infant without severe postnatal complications is expected to sustain nutritional needs by mouth at which postnatal week without supplementation?

• A. Immediately after birth
• B. 2 weeks after birth
• C. 4 weeks after birth
• D. 6 weeks after birth

Answer: (C)

Maturation of oral feeding in preterm infants depends on postmenstrual age—the combination of gestational age at birth and time since birth. A baby born at 30 weeks typically develops enough suck–swallow–breathe coordination to sustain by-mouth nutrition around 34 weeks postmenstrual age. That occurs about four weeks after birth for this infant. When they reach this PMA and have stable breathing and no major complications, they can feed by mouth without supplementation. Feeding immediately after birth or at earlier postnatal ages is usually not yet coordinated, and waiting until six weeks postnatal would place them at roughly 36 weeks PMA, past the common readiness window.
