Colostrum also contains growth factors and hormones that promote healthy growth and development in infants.
Furthermore, colostrum acts as a natural laxative, aiding in the passage of meconium, the infant’s first stool. It helps to clear the gastrointestinal tract and establish a healthy bacterial population in the gut.
It is recommended that infants receive colostrum within the first hours after birth to maximize its benefits. However, if the mother is unable to breastfeed immediately or if there is an insufficient supply of colostrum, it can be expressed and stored for future use.
Storing Colostrum
Colostrum can be stored in the refrigerator for up to 72 hours. It is crucial to store it in clean, sterile containers to prevent bacterial contamination. Using breast milk storage bags or sterile containers with tight-fitting lids is recommended. It is also important to label the containers with the date and time of expression to ensure proper rotation.
Note: Colostrum may separate and form layers when refrigerated. This is normal and does not indicate spoilage. Gently swirling or shaking the container before feeding will help to mix the layers back together.
Using Stored Colostrum
When using stored colostrum, it is essential to warm it by placing the container in warm water or a bottle warmer. Avoid using a microwave, as it can destroy some of the beneficial components of colostrum and create hot spots that may scald the infant’s mouth.
Note: Colostrum that has been thawed should be used within 24 hours. Discard any leftovers to maintain freshness.
In conclusion, colostrum is a vital source of nutrition and immune protection for newborns. Understanding how to store and use colostrum properly is essential for ensuring its benefits are maximized. By following proper storage and handling techniques, parents can provide their newborns with the valuable nutrients and antibodies found in colostrum.
