At approximately what gestational age can suckling and swallowing sustain nutritional needs in a healthy infant?

• A. 32 weeks
• B. 34 weeks
• C. 36 weeks
• D. 38 weeks

Answer: (B)

Oral feeding depends on coordinated suck, swallow, and breathing. As the nervous system and oral-motor structures mature, preterm infants begin to coordinate these actions well enough to take in enough milk by mouth. This coordination typically becomes adequate around the late preterm period, about 34 weeks gestation. Before this point, the suck–swallow–breath pattern is less mature, so many infants cannot sustain nutrition orally and need tube feedings or supplemental support. After about 34 weeks, most healthy infants can meet their nutritional needs through suckling and swallowing with breathing, making oral feeding reliably possible.
