The Science of Breastfeeding – What New Mothers Should Know

The Science of Breastfeeding – What New Mothers Should Know

Becoming a mother is one of life’s most profound transitions—and along with the flurry of emotions, advice, and new routines comes one of the most important decisions you'll make in your baby’s early life: how to feed them.

For centuries, breastfeeding has been the gold standard, yet in today’s world, the landscape of infant feeding has become more nuanced. Breastfeeding is often called “liquid gold” for a reason. It’s a biologically engineered superfood made perfectly for your baby. But beyond the poetic phrasing, there’s a mountain of science backing its benefits—for both baby and mum. 

Understanding the science behind breastfeeding and finding trusted guidance can help you make empowered, informed choices that best suit your unique situation. To support new mothers on this important journey, CradleNest has partnered with experienced lactation consultant, Mayvina, from Manna Milk Lactation. Mayvina offers personalized, evidence-based guidance from pregnancy through the fourth trimester and beyond. Her compassionate approach addresses challenges such as engorgement, mastitis, low supply, latch issues, and more, ensuring you receive the support you need to achieve your breastfeeding goals

Why Breastfeed? The Evidence-Based Benefits

For the Baby: The Protective Power of Breast Milk

Breastfeeding has unparalleled health benefits for babies that go far beyond nutrition. It’s a direct line to your baby’s immune system, offering them protection against a wide array of diseases and illnesses.

Immune System Support

Colostrum, the first form of milk produced by the breasts, is a powerhouse of antibodies. This yellowish, nutrient-rich liquid is packed with white blood cells, proteins, and immunoglobulins that provide newborns with critical immune protection in their early days of life. Singapore, with its tropical climate and high population density, creates an environment where respiratory infections and gastrointestinal diseases can spread more easily. Breastfeeding plays a pivotal role in protecting babies from these illnesses. According to the Singapore Health Promotion Board (HPB), breastfed infants are less likely to be hospitalized for infections, with breastfeeding providing the first line of defence against infections like pneumonia, diarrhoea, and ear infections.

Cognitive Development

Breast milk isn’t just food…it’s brain food! It contains important fats and nutrients, such as DHA (docosahexaenoic acid), an omega-3 fatty acid that plays a crucial role in brain development. Studies, including research from Singapore’s National University Hospital (NUH), confirmed that breastfeeding improves cognitive development, IQ, and long-term learning outcomes in later childhood.

For the Mother: Physical and Emotional Health Benefits

Mothers in Singapore, particularly in urban environments, often balance demanding work and family life. The decision to breastfeed can have profound physical and emotional effects that support both maternal health and recovery.

Postpartum Recovery

For new mothers, especially those recovering from a caesarean section or an extended labour, breastfeeding can aid in the physical healing process. The release of oxytocin, triggered during breastfeeding, helps the uterus contract, reducing postpartum bleeding. This effect speeds up recovery, making it easier for mothers to adjust to the demands of life with a newborn.

Emotional Bonding

Breastfeeding fosters emotional bonding through the close physical contact between mother and child. This bond, facilitated by oxytocin, plays a key role in reducing stress and promoting emotional wellbeing. A mother’s mental health is supported through the physical touch, eye contact, and the nurturing interaction that breastfeeding offers. In fact, research shows that mothers who breastfeed tend to report lower rates of postpartum depression.

Breastfeeding Woes – Milk Supply, Latching, and Newborn Feeding Behaviour

Milk Supply: More Than Just a Biological Function

A common concern among new mothers is the worry about insufficient milk supply. However, understanding the mechanics behind milk production can alleviate these anxieties. Milk production is primarily a demand and supply system: the more frequently your baby nurses or you pump, the more milk your body will make.

Research indicates that most mothers will produce enough milk by day 3 to 5 postpartum, as colostrum gradually transitions to mature milk. Factors like frequent breastfeeding, skin-to-skin contact with the baby, and minimizing the use of formula can all help increase milk supply.

New mothers can expect your baby to nurse 8 to 12 times in 24 hours, especially during the first few weeks. This frequent feeding ensures both optimal growth and milk production. In the first days of life, a baby’s stomach is tiny, just about the size of a cherry, so frequent feeds are necessary to ensure they get enough nourishment.

Latching: The Key to Comfort and Effective Feeding

A good latch is crucial for successful breastfeeding. A poor latch can cause nipple pain, lead to engorgement, and even reduce the amount of milk the baby is able to take in. 

Signs of a good latch include:

·   Baby’s mouth should cover a large portion of the areola (not just the nipple).

·   The chin should be pressed into the breast, with the nose free.

·   You should hear rhythmic sucking and swallowing sounds.

·   The baby’s cheeks should not dimple inward during sucking.

If you are unsure whether your latch is correct, seeking help from a lactation consultant early on can prevent future issues and ensure both you and your baby are comfortable during feeds. Mayvina, from Manna Milk Lactation, offers expert lactation support for Singaporean mothers, providing with guidance backed by extensive experience.

 

Newborn Feeding Behaviour: Understanding Baby’s Needs

Newborns are biologically programmed to nurse frequently. This behaviour is driven by their need for nourishment and their tiny stomachs, which can only hold small amounts of milk at a time.

Understanding your baby’s feeding cues like sucking on their hands, rooting, or becoming fussy, can help you respond promptly before they become too upset. Feeding on demand rather than following a strict schedule ensures your baby receives enough milk and encourages a healthy milk supply.

Empowering Your Breastfeeding Journey

Breastfeeding is an extraordinary biological function, a nurturing bond, and an essential foundation for your baby’s health and development. The science is clear: breastfeeding offers unmatched physical and emotional benefits for both mother and child. However, every mother’s feeding journey is unique, and there is no one-size-fits-all approach.

Whether you choose exclusive breastfeeding, combination feeding, or any other method, the best decision is the one that works for you and your baby. By understanding the science of breastfeeding, seeking support when needed, and trusting your instincts, you can make informed, confident decisions about your feeding journey.
