Thoughts About Harvesting Colostrum
To Harvest or Not to Harvest Colostrum? Here’s What You Need to Know as You Plan for Breastfeeding Success
As a second-time mom and an experienced dietitian and IBCLC (International Board Certified Lactation Consultant), I’m excited to share my journey and insights on harvesting colostrum before birth. If you’re planning to breastfeed or chestfeed, working with an IBCLC during pregnancy can significantly boost your success. (Lets Talk HERE) This post provides some evidence for you to consider, along with practical steps to get started. (As always, this information is not a substitute for medical advice. Discuss your plan with your healthcare provider first!)
What’s the Buzz About Colostrum Harvesting?
If you’re pregnant, you may have heard about the potential benefits of harvesting colostrum — but you might wonder, what’s the point? Can expressing colostrum before birth actually make a difference? And is it safe?
Here’s what we know so far:
What’s Going On with Colostrum?
The human body is incredible. By around 16 weeks of pregnancy, most people are already producing colostrum, a thick, nutrient-dense milk packed with antibodies. Colostrum serves as a first line of defense, especially if a newborn faces any challenges after birth. Many people who are already breastfeeding may continue to do so during pregnancy, though the supply often decreases due to hormonal changes that prioritize the pregnancy.
After birth, the delivery of the placenta triggers a hormonal chain reaction that signals the body to produce a mature milk supply. Colostrum, however, is available immediately and can be very beneficial for your newborn.
Can Expressing Colostrum Early Trigger Labor?
Expressing colostrum before birth can occasionally stimulate uterine contractions. This effect is similar to the natural cramping some people experience during breastfeeding in the first days after giving birth, as breastfeeding helps the uterus contract back to its pre-pregnancy size.
For safety, it’s generally recommended to wait until at least 35 weeks before beginning hand expression of colostrum, and 37 weeks for pumping. If you’re on pelvic rest or advised to avoid nipple stimulation, it’s essential to follow that guidance. Gentle hand expression usually doesn’t cause stronger contractions than those caused by an orgasm, but using a hand pump or electric pump might be more intense. Always consult your healthcare provider to ensure the timing and method are safe for your individual pregnancy.
Benefits of Colostrum Collection
For Baby: Colostrum is especially helpful for babies who might need extra support at birth, such as those with low blood sugar or difficulties breastfeeding immediately. Having this rich milk on hand can ease the transition to breastfeeding if challenges arise, providing them with essential nutrients and immunity-boosting properties.
For Chestfeeding Parent: Colostrum harvesting helps you become familiar with your breasts, building confidence in your body’s ability to provide for your baby. Most people aren’t used to the sensation of breastfeeding multiple times a day. By practicing expression beforehand, you’ll be better prepared to handle this new experience.
Step-by-Step Guide to Colostrum Harvesting
When to Start:
Begin hand expressing at 35+ weeks if cleared by your healthcare provider.
Start using a hand pump or electric pump at 37+ weeks if approved.
How Long to Express:
Aim for 5–10 minutes on each side, 2–3 times a day.
How to Collect and Store Colostrum:
Collection: Use a needleless syringe to draw up the colostrum drops.
Storage: Store collected colostrum in the refrigerator for up to 4 days. After 4 days, transfer it to the freezer.
Labeling: Place each syringe in a zip-lock bag with your name, date of birth, amount, and collection date clearly labeled.
Freezing: Once in the freezer, store syringes until you’re ready to bring them to the hospital or birthing center. Proper labeling helps ensure that your colostrum is ready to use for your baby’s first feeds.
