breastfeedingHormonally driven at firstLactogenesis I colostrumLactogenesis II increase in milk volume after birthMilk maintenance (supply demand)Lactogenesis III Milk removalEmpty breast = milk productionFull breast = slower milk production

Breastfeeding preemiesMilk production as part of hormones during pregnancy Midway through start making colostrumDelivery of placentaNeed to express breastmilk to produce breastmilkWeak suck, endurance, immature digestive systemNGT deliveryHerbs, medications Respiratory systemMaintain a balance of oxygen and carbon dioxide

AspirationaspirationPenetration of secretions or any foreign particulate substances beyond the laryngeal inlet into the tracheobronchial treeThreatens lower airwaysFrequency, amount and properties of aspirateRed flagsFactors that can contribute to aspiration

Gastroesophageal refluxThe return of gastric contents, either food alone or mixed with stomach acid, into the esophagus. Reflux is normal!
