Breastfeeding While Pregnant: Is It Safe?

Breastfeeding during pregnancy is possible for many women, but it's not without its challenges. It may require changes in positioning and scheduling, and it's important to ensure adequate nutrition for both mother and child. While it's generally safe, it can be risky for some women, particularly those with high-risk pregnancies or a history of early miscarriages. Breastfeeding can cause contractions, which may be a concern for those with a history of preterm labour or miscarriage. However, research suggests that breastfeeding is compatible with healthy term births, and it is not necessarily a cause for concern.

Breastfeeding during pregnancy may be safe, but it's not recommended for women with high-risk pregnancies

Breastfeeding during pregnancy is a complex issue that requires careful consideration and consultation with healthcare professionals. While it may be safe for many women, it is not recommended for those with high-risk pregnancies. Here's a more detailed look at the topic:

Breastfeeding During Pregnancy: Is It Safe?

Breastfeeding during pregnancy, also known as breastfeeding during pregnancy (BDP), is a personal decision that requires a case-by-case evaluation. While it is possible and safe for many women, it is not without its challenges and potential risks. One of the primary concerns is the release of the hormone oxytocin during breastfeeding, which stimulates uterine contractions and could potentially affect pregnancy outcomes. However, recent studies suggest that breastfeeding is compatible with healthy term births, and the risk of preterm labour or miscarriage is relatively low in healthy pregnancies.

The Benefits of Breastfeeding During Pregnancy

Breastfeeding has numerous benefits for both the mother and child. Human milk provides important nutritional and immunological boosts for children, and weaning before the age of two can increase the risk of illness. Breastfeeding can also facilitate the adjustment of an older child to a new baby and promote mother-child attachment. Additionally, breastfeeding can be a relaxing and comforting experience for tired and pregnant mothers.

Special Considerations for High-Risk Pregnancies

Women with high-risk pregnancies, including those with a history of early miscarriages, recurrent pregnancy loss, bleeding during pregnancy, or preterm labour, should carefully consider the risks of breastfeeding. While there is no definitive evidence that breastfeeding triggers preterm labour or miscarriage, the oxytocin release associated with nipple stimulation could potentially impact uterine activity and contractions. As such, healthcare professionals may advise against breastfeeding during pregnancy for women in these high-risk categories.

Nutritional Requirements and Strategies for Breastfeeding During Pregnancy

Breastfeeding during pregnancy requires meeting the nutritional needs of both the mother and the developing fetus. Pregnant women who breastfeed should aim for an additional 500 to 650 extra calories per day, depending on the age of their older child. They should also be prepared for potential breast tenderness, nipple sensitivity, and changes in milk supply and taste, which may cause older children to self-wean. Consulting with a lactation consultant can provide invaluable advice and support for successful breastfeeding during pregnancy.

Breastfeeding during pregnancy may be safe for many women, but it is not recommended for those with high-risk pregnancies. It is essential to consult with healthcare professionals, including obstetricians and lactation consultants, to make an informed decision that considers individual circumstances and health needs.

Breastfeeding and contractions: nipple stimulation releases oxytocin, which causes uterine contractions

Breastfeeding during pregnancy is a common practice, with 61% of mothers who breastfed for at least six months continuing to do so during a subsequent pregnancy. However, there are concerns about the safety of this practice, particularly regarding the risk of preterm labour and miscarriage.

One concern is that breastfeeding causes contractions, which could potentially trigger preterm labour or miscarriage. Nipple stimulation releases the hormone oxytocin, which causes the contraction of breast tissue to eject milk. Oxytocin also causes the contraction of uterine tissue. However, the release of oxytocin in response to nipple stimulation is lower during pregnancy than when a woman is not pregnant.

The uterus is well-protected from untimely labour during the "preterm" period. It is geared towards having a muffled response to oxytocin while the baby is growing and only becomes responsive to it at term. The uterus must also be actively prepared for labour, and certain agents are required for oxytocin receptor sites to respond strongly to oxytocin. Furthermore, natural oxytocin-blockers like progesterone prevent oxytocin from reaching its receptor sites during pregnancy.

Research suggests that breastfeeding is compatible with healthy term births. A survey of 57 California mothers who breastfed during pregnancy found no adverse consequences to their pregnancies. There are also many anecdotal reports of mothers who breastfed throughout their pregnancy and gave birth to healthy, full-term babies.

While breastfeeding can cause contractions, most mothers do not notice them, even during pregnancy. Even those who experience intense "nursing contractions" often find that the contractions stop soon after the breastfeeding session ends.

In conclusion, while breastfeeding during pregnancy can cause contractions due to the release of oxytocin, the available research suggests that it is unlikely to trigger preterm labour or miscarriage. The uterus is well-protected during the preterm period, and contractions associated with breastfeeding do not usually disrupt the pregnancy.

The well-protected uterus: oxytocin receptor sites are sparse until 38 weeks, and natural oxytocin-blockers like progesterone are present during pregnancy

The uterus is well-protected from the effects of oxytocin during pregnancy, particularly during the "preterm" period of 38 weeks. This is due to several factors that prevent the hormone from triggering labour prematurely.

Firstly, there are fewer oxytocin receptor sites in the uterus during pregnancy. These receptor sites, found on uterine cells, detect the presence of oxytocin and cause contractions. However, these sites are sparse until 38 weeks into the pregnancy, gradually increasing after this point and then increasing 300-fold once labour has begun. The scarcity of these sites is a crucial defence mechanism that keeps the uterus in a quiescent, baby-holding state during the preterm period.

Secondly, oxytocin receptor sites are down-regulated during pregnancy, meaning they require the help of "gap junction proteins" to respond strongly to oxytocin. Without these proteins, the uterus is relatively insensitive to oxytocin, providing further protection against premature contractions.

Finally, natural oxytocin-blockers like progesterone are present during pregnancy, further inhibiting the effects of oxytocin. Progesterone stands between oxytocin and its receptor sites, acting as another line of defence against untimely contractions and preterm labour.

In summary, the combination of sparse and down-regulated oxytocin receptor sites, along with the presence of natural oxytocin-blockers, ensures that the uterus remains in a protected, baby-holding state during pregnancy. This intricate balance of hormonal interactions allows for a safe and healthy pregnancy, reducing the risk of preterm labour or miscarriage.

Tips for breastfeeding during pregnancy: positioning and scheduling changes, managing breast/nipple tenderness, and maintaining a healthy diet

Tips for breastfeeding during pregnancy

Positioning and scheduling changes

• Nursing your baby around every one and a half to three hours is a good way to bring in milk, provide the baby with the fluid it needs, and help the baby's digestive system.
• The baby's body should be turned toward you, with the baby's tummy against your tummy and the baby's knees against your stomach. This prevents the baby's mouth from slipping and helps keep your nipples from getting sore.
• Touching the baby's lower lip will usually make its mouth open wide. You can then bring the baby to your breast to latch.
• After about 10 to 15 minutes, gently put your little finger in the corner of the baby's mouth and push to break the suction. Then switch to the other breast and let the baby nurse for another 10 to 15 minutes.
• Babies don’t follow set schedules and may not nurse the same amount of time at each feeding. Most babies need and want about 10-12 feedings every 24 hours. It is okay to nurse about every one and a half hours.
• Try different feeding positions such as the football hold or modified cradle hold to facilitate latching onto the breast. These positions provide better control of your baby's head and achieve a good latch.

Managing breast/nipple tenderness

• Nipple soreness usually goes away after a few days. Most mothers find that it peaks on the fifth day of breastfeeding and then resolves.
• If putting your baby to your breast is too painful, use a breast pump or hand-express to keep your milk supply flowing.
• Your breast milk can help your nipples heal with antibacterial protection. If you have a cracked nipple, squeeze out a few drops of milk and gently rub it over your nipple. Let your nipples air dry before covering them.
• Try using warm, moist heat on your sore nipples. Run a clean washcloth or cloth diaper under warm (not hot) water, squeeze out the extra water, and place it directly over your nipple. When it cools, repeat the process.
• Try hand-expressing a small amount of milk and gently rubbing or patting it into your nipple. Let it air dry before putting your nursing bra back on.
• Reverse pressure softening can be helpful if there is a lot of swelling in the breast. Using gentle pressure from one or two fingers around the nipple base can move some of the swelling away from the nipple.
• If your nipple pain persists for more than seven days, goes away and then returns, or your nipples are bleeding, see your lactation consultant or healthcare provider for an evaluation.
• Try using purified lanolin cream on sore nipples to promote healing. You can also wear a breast shell between feedings to protect sore nipples from rubbing against your clothing.
• If you have inverted nipples, consult your doctor. They may recommend using a niplette as a non-surgical correction from 12 weeks of pregnancy onwards.
• Get a supportive bra to help you feel more comfortable as your breasts grow. Consult a bra-fit expert, and consider a cotton sports bra to sleep in if your breast size increases significantly.
• Avoid tight bras and bras with underwires. Instead, opt for softly padded cotton bras. Underwired bras tend to hamper milk production by blocking the milk ducts.
• Your nipples may get dry and crack during pregnancy, so it's important to retain moisture. You can use olive or coconut oil and gently massage your nipples before bathing.
• Nipples tend to leak colostrum, especially during the last trimester. Change your bra regularly to avoid the nipples becoming too wet, which may lead to cracks and infections. You can also use breast pads to keep your nipples dry.
• Always wash your nipples regularly to prevent the liquid from forming a crust around them.
• Avoid using soap on the nipple during your daily baths, as it tends to dry out the nipples and can lead to cracking.
• After you shower, apply some moisturising cream to your nipples if they feel too dry.
• Some women may benefit from using nipple protectors, which can be used as a pad between the clothing and the nipples to prevent soreness.
• Organic coconut oil can be a beneficial and natural solution for breast and nipple care during pregnancy. It has moisturising and anti-inflammatory properties that can help prevent dryness, itchiness, and irritation. Gently massage it onto your breasts and nipples after a shower or bath.
• Invest in soft and absorbent breast or nursing pads to place inside your bra. These pads can help absorb any colostrum or breast milk leakage, keeping your nipples and bra dry and preventing irritation.

Maintaining a healthy diet

• You will need to take in about 500 extra calories each day to help you produce good breast milk. Otherwise, your diet should be like the diet recommended during pregnancy.
• To be sure you are not getting too many calories, watch your weight. You should not gain weight at this time.
• Avoid using lotions or alcohol on your breasts. You can do normal cleaning of the breasts when bathing or showering.
• Avoid alcohol and smoking while you are pregnant and even later when breastfeeding.

Weaning your older child when you're pregnant: your milk supply may decrease, and the taste may change, causing your child to wean themselves

Weaning an older child when you're pregnant can be challenging, and you may experience a decrease in your milk supply. This is due to the hormonal changes that occur during pregnancy, specifically the rise in progesterone levels, which can make the alveoli "leaky" and unable to store milk effectively. This can lead to a reduction in milk supply by mid-pregnancy or even as early as the first month.

The taste of your milk may also change during pregnancy, which can cause your child to wean themselves. The flavour of breast milk is influenced by the foods you eat, and during pregnancy, your milk may take on a different taste due to hormonal shifts. Some nursing toddlers may notice and comment on this change, and it could lead to them weaning.

The process of weaning an older child during pregnancy can be gradual, and it's important to be sensitive to your child's needs. You can try dropping one feeding session per week and offering other sources of nourishment, such as solid foods or formula, to help your child adjust. It's also crucial to ensure your child is getting enough nutrients, especially if they are under one year old, as milk should be their primary source of nutrition.

Remember, the decision to wean is a personal one, and it's important to consider the physical and emotional needs of both you and your child. Weaning can be an emotional process, as it signifies a milestone and the end of an intimate bonding activity. Seeking support from family, friends, or local support groups can be beneficial during this time.
