Impact of Oropharyngeal Colostrum Therapy on Early Nutritional Maturation, Enteral Transition, and NICU Recovery Outcomes in Very Preterm Infants: A Randomized Controlled Trial
This randomized controlled trial demonstrates that an 8-day oropharyngeal colostrum therapy protocol significantly accelerates enteral feeding progression, enhances early growth velocity, and reduces the incidence of sepsis and necrotizing enterocolitis in very preterm infants without adverse events.

Every baby born too early faces a race against time, not just to grow, but to learn how to digest food. For infants born before thirty-three weeks, their digestive systems are often as undeveloped as their lungs. Because they cannot eat by mouth safely, doctors must feed them through a tube directly into the stomach or, in the most fragile cases, through an intravenous line that bypasses the gut entirely. This reliance on liquid nutrition delivered straight into the bloodstream carries risks, including severe infections and inflammation of the bowel. The goal for medical teams is to get these tiny patients eating normally as soon as possible, but the transition is often slow and fraught with setbacks. For decades, researchers have known that a mother's first milk, known as colostrum, is a powerful biological substance. It is thick, yellow, and packed with immune-protective factors that act like a shield for a newborn's gut. While feeding this milk into a baby's stomach is standard practice, a newer idea suggests that simply letting the milk touch the inside of the baby's mouth might be enough to wake up the digestive system and prepare it for food.
A team of researchers in Iran set out to test whether this simple act of touching the mouth with colostrum could change the course of recovery for very premature babies. They conducted a controlled study involving ninety-one infants born before thirty-three weeks and weighing less than 1,800 grams. The babies were divided into two groups. One group received the standard care found in neonatal intensive care units, while the other group received a specific treatment: a small amount of their own mother's colostrum was gently applied to the inside of their cheeks every six hours for eight days. The amount used was tiny, just enough to coat the mouth, and the procedure was designed to mimic the natural stimulation a baby gets from sucking, without actually feeding them the milk. The researchers monitored the babies closely to see if this early contact with the protective milk helped their bodies adapt to eating sooner.
The results showed a clear difference in how quickly the babies in the treatment group moved toward full feeding. Infants who received the colostrum application started eating through their stomach tubes about six days after birth, whereas those in the standard care group waited until their twelfth day. More importantly, the treatment group reached the milestone of eating all their nutrition by mouth or tube without needing intravenous support much faster. They achieved full feeding in a median of eighteen days, while the other group took twenty-five and a half days. This acceleration meant the babies in the treatment group were growing at a significantly better rate, gaining weight at a speed of roughly 9.5 grams per kilogram of body weight each day, compared to just over 5 grams for the others. The study also noted that the babies receiving the colostrum treatment required fewer sessions of specialized oral motor therapy to learn how to suck and swallow, suggesting their mouths and digestive tracts were maturing more naturally.
Beyond just feeding and growth, the study observed that the babies receiving the colostrum application appeared to be healthier overall during their hospital stay. They spent less time on antibiotics, with a median treatment duration of ten days compared to eighteen days for the control group. The researchers also found that the treatment group had far fewer cases of serious infections and bowel inflammation. Only about 7 percent of the treated babies developed necrotizing enterocolitis, a severe and dangerous bowel disease, compared to nearly 32 percent of the babies who did not receive the colostrum application. Similarly, confirmed cases of sepsis, a life-threatening blood infection, were much lower in the group that received the mouth treatment. While the study was designed primarily to measure feeding speed, these secondary findings of reduced illness and faster recovery suggest that the simple act of exposing the mouth to colostrum may offer broad protective benefits.
The researchers were careful to note that while the results are promising, the study was conducted at a single medical center and involved a relatively small number of babies. Because the study was not originally designed to prove the reduction in infections, the authors describe these findings as encouraging but in need of confirmation by larger, multi-center trials. They also emphasized that the procedure was safe, with no adverse events like breathing pauses or heart rate changes linked to the treatment. The study concludes that applying a mother's first milk to the mouth of a very premature infant is a feasible and safe way to help the baby's digestive system mature faster, potentially shortening the time these vulnerable children spend in the hospital and reducing their exposure to serious complications.
