The coordination of sucking, swallowing, and breathing becomes adequately developed for successful oral feeding at approximately how many weeks of gestation?

• A. 28 weeks
• B. 34 weeks
• C. 40 weeks
• D. 22 weeks

Answer: (B)

The ability to safely feed orally relies on mature coordination of the suck, swallow, and breathing pattern. By about 34 weeks gestation, the neural and motor systems controlling the oral–pharyngeal muscles and airway protection have developed enough to coordinate these actions in a stable rhythm, reducing the risk of aspiration during feeds. Earlier in gestation, such as around 22–28 weeks, swallow–breathe coordination is immature, making safe oral feeding unlikely. By term (around 40 weeks), the system is more than sufficient, but the question asks for the approximate point when this coordination becomes adequate, which is around 34 weeks.
