Starting breast pumping at 37 weeks is generally safe and can help prepare for breastfeeding and milk supply, but consult your healthcare provider first.
Understanding Breast Pumping at 37 Weeks
Breast pumping late in pregnancy, specifically at 37 weeks, is a topic many expectant mothers consider as they prepare for their newborn’s arrival. At this stage, the baby is considered full term, and the body is gearing up for labor and delivery. Pumping can stimulate milk production, help mothers become familiar with their breast pump, and even collect colostrum—the nutrient-rich first milk that nourishes newborns.
However, it’s crucial to understand the physiological and medical implications before starting. Pumping at 37 weeks isn’t just about convenience; it can influence hormone levels that trigger contractions. Oxytocin, released during pumping, can cause uterine contractions similar to labor. For most women with uncomplicated pregnancies, this stimulation is safe. But for those with risks like preterm labor history or placenta complications, caution is necessary.
Why Consider Pumping Before Birth?
Many moms-to-be choose to pump before their baby arrives for several reasons:
- Colostrum Collection: Early pumping allows you to harvest colostrum in small amounts to store for feeding if the baby struggles initially.
- Milk Supply Preparation: Stimulating breasts before birth can jumpstart milk production.
- Pump Familiarization: Learning how to use a breast pump effectively reduces stress postpartum.
- Medical Necessity: In some cases, babies born prematurely or with health issues may need expressed milk immediately.
Pumping before birth isn’t mandatory but can be a proactive step for mothers planning exclusive breastfeeding or those anticipating challenges.
The Science Behind Late-Pregnancy Pumping
Hormones play a starring role in lactation readiness. As pregnancy progresses past 36 weeks, the body increases prolactin levels (responsible for milk production) and oxytocin (which causes milk ejection). When you pump, oxytocin release mimics the natural breastfeeding process by stimulating nipple receptors.
This hormonal surge can induce mild uterine contractions called Braxton Hicks. These are generally harmless but may sometimes escalate into true labor contractions, especially if the cervix is sensitive or there are underlying complications.
Medical professionals often advise caution starting pumping after 36 weeks because of this risk. Yet many hospitals encourage “antenatal expressing” under supervision when medically appropriate—especially for women with diabetes or other conditions affecting newborn feeding.
The Role of Colostrum
Colostrum is thick and yellowish—packed with antibodies and nutrients essential for newborn immunity. It’s produced in small quantities late in pregnancy and during the first few days postpartum.
Collecting colostrum via pumping at 37 weeks allows you to store these precious drops ahead of time. This stored colostrum can be invaluable if your baby experiences feeding difficulties or needs supplemental nutrition in the first days.
Is It Safe To Start Pumping At 37 Weeks?
The short answer: yes, but only under certain conditions.
Healthcare providers typically recommend starting antenatal pumping only if:
- Your pregnancy is low-risk without signs of preterm labor.
- You have been cleared by your obstetrician or midwife.
- You understand proper techniques to avoid overstimulation.
Women with high-risk pregnancies—such as placenta previa, cervical insufficiency, or history of premature birth—should avoid antenatal pumping unless directed by a specialist.
When done correctly, pumping sessions should be brief (about 5-10 minutes per breast) once or twice daily. Over-pumping may cause excessive uterine contractions or nipple soreness.
Medical Guidelines on Antenatal Expressing
Several studies have explored antenatal expressing safety and benefits:
| Study/Organization | Key Findings | Recommendations |
|---|---|---|
| Cochrane Review (2017) | No significant increase in preterm labor risk among low-risk women starting antenatal expressing at 36+ weeks. | Pumping should be supervised; avoid excessive duration/frequency. |
| Royal College of Obstetricians & Gynecologists (RCOG) | Antenatal expressing safe after 36 weeks if medically indicated (e.g., diabetic mothers). | Pump once daily; monitor contractions closely. |
| Australian Breastfeeding Association | Antenatal expressing helps build confidence; collects colostrum for early use. | Consult healthcare provider; start only if no complications present. |
These guidelines reinforce that while starting to pump at 37 weeks is generally safe for healthy pregnancies, medical advice remains critical.
How To Start Pumping Safely At 37 Weeks
If you decide to begin antenatal pumping at this stage, follow these practical steps:
Select The Right Equipment
Choosing an efficient yet gentle breast pump matters. A double electric pump with adjustable suction levels works well. Avoid overly strong suction settings that can cause discomfort or nipple trauma.
Pumping Technique And Schedule
- Duration: Limit sessions to about 5-10 minutes per breast initially.
- Frequency: Once daily is sufficient when starting out; some increase to twice daily after consulting their provider.
- Suction Level: Use a comfortable setting that mimics natural nursing without pain.
- Mild Stimulation: Gently massage breasts before and during pumping to encourage flow.
- Mild Contraction Monitoring: Pay attention to any tightening sensations; stop if contractions intensify or become painful.
Storing Colostrum Safely
If you collect colostrum while pumping antenatally:
Frozen colostrum remains viable for months when stored properly in deep freeze conditions.
The Benefits Of Starting Pumping At 37 Weeks
Starting early brings several advantages beyond just collecting milk:
- Eases Transition Postpartum: Familiarity with pumps reduces anxiety after delivery when time is precious.
- Makes Milk Supply More Robust: Early stimulation signals your body to ramp up production faster once baby arrives.
- Saves Time During Hospital Stay: Having stored colostrum means immediate feeding support without delay from supply issues.
Moreover, this practice empowers moms who might face challenges like cesarean sections or babies admitted to NICU requiring expressed milk feeds initially.
The Risks And Precautions Of Antenatal Pumping At 37 Weeks
Despite benefits, there are risks worth considering:
- Cervical Changes And Labor Induction: Oxytocin release might lead to premature cervical dilation or trigger early labor in sensitive cases.
That’s why constant monitoring by your healthcare team is essential when starting antenatal expressing late in pregnancy.
Other risks include nipple soreness from improper technique and emotional stress if pumping doesn’t yield expected results immediately.
Troubleshooting Common Issues During Antenatal Pumping
- No Milk Expression Initially: This is normal since full lactation hasn’t started yet; keep trying gently without forceful suction.
- Pain Or Discomfort: Adjust suction level or try different flange sizes on your pump; consult lactation support if pain persists.
- Braxton Hicks Contractions:If they become regular or painful stop pumping immediately and contact your provider.
The Emotional Impact Of Starting Pumping At This Stage
Getting ready emotionally plays a big role too. Many moms feel empowered taking proactive steps like antenatal expressing—it gives a sense of control amidst pregnancy uncertainties.
Still, it’s normal to feel frustrated if progress seems slow or challenging. Support from partners, lactation consultants, and healthcare providers helps keep morale high while navigating this new experience.
The Role Of Healthcare Providers In Guiding Antenatal Expressing
Open communication with your obstetrician or midwife ensures safety throughout this process. They will assess your individual risk factors and advise whether starting pumping at 37 weeks suits your specific situation.
Sometimes hospitals have protocols supporting antenatal expressing classes where nurses guide correct techniques safely under supervision—a great resource!
