5 Science-Backed Benefits of Breastfeeding Over Formula Feeding

In short: Breastfeeding has five proven benefits: it strengthens the baby’s immunity and protects against infection; it is easier to digest and reduces diarrhoea and vomiting; the baby controls the amount taken; a study of 17,000 children linked it to higher IQ; and it lowers the risk of sudden infant death. If direct breastfeeding is not possible, expressed breast milk is better than formula.

As a new mother, you will be faced with a barrage of information. Almost everyone you know will have an opinion about everything, right from what you should eat to how you should care for your baby. One especially important and sometimes debated topic is breastfeeding. Some believe that only a breastfed baby can develop fully, while other mothers prefer formula, finding it more convenient and easier to manage. So who is right, and what does the research actually say? Here are five reasons why breastfeeding a baby may offer advantages over formula feeding.

1. Breastfeeding Builds Immunity

A baby is most vulnerable to illness during the first few months of life. Studies suggest that breastfeeding may help reduce the chances of contracting certain communicable diseases, which can otherwise limit your baby’s development during this crucial period. Antibodies naturally present in breast milk are thought to play a major part. Breastfeeding may also support the strength of your baby’s developing immune system, helping to keep your little one healthier.

2. Easily Digestible

No parent wants their baby to struggle with indigestion or gut discomfort. This is a common concern associated with baby formula, which can sometimes be harder for an infant to digest. Breast milk, on the other hand, is rich in nutrients and comes from a source the baby’s body already recognizes, making it generally easier to digest. This can mean high-quality nutrition for your baby, with a lower likelihood of issues like diarrhea and vomiting.

3. Baby-Determined Quantity

Unlike bottle feeding, where you decide how much your baby is fed, breastfeeding is naturally led by the baby. Your baby will typically stop feeding when full, which can help prevent overfeeding. Because breastfeeding follows a natural cycle, the amount of milk being produced tends to align with your baby’s needs — as your baby’s needs change, milk production adjusts accordingly. Additionally, breast milk contains exactly the amount of protein a baby needs — less than formula or cow’s milk — together with the right balance of fats and natural milk sugar (lactose), which supports healthy growth and may lower the risk of excess weight gain later in childhood.

4. Cognitive Development

One argument often made in favor of breastfeeding is its possible link to cognitive development. Some studies suggest that breastfed babies may show different developmental patterns compared to formula-fed babies. In one notable survey of over 17,000 infants followed from birth to age six, researchers observed differences in cognitive test scores associated with exclusive breastfeeding. As with all observational research, these findings should be interpreted with care, since many factors influence a child’s development.

5. Reduced Risk of SIDS

The risk of Sudden Infant Death Syndrome (SIDS) may be lower in breastfed babies, according to some research. While SIDS remains a largely unexplained phenomenon, a German study found an association between breastfeeding and reduced SIDS risk — babies breastfed for at least the first month showed notably lower risk compared to those who were bottle-fed. Reduced infection risk and immune support may play a role here as well. The World Health Organization, UNICEF, the American Academy of Pediatrics and the US Centers for Disease Control and Prevention recommend feeding your baby only breast milk for the first 6 months, then continuing to breastfeed alongside solid foods until 2 years of age or beyond.

Breastfeeding is also often described as helping build a close emotional bond between mother and child.

It can be a practical and cost-effective choice, since breast milk is available anytime, anywhere, at no direct cost.

Forced Bottle Feeding

There are times when a mother may need to temporarily pause direct breastfeeding due to physical or medical reasons. In these situations, it’s often recommended to pump breast milk into a bottle rather than switch straight to formula. Formula can be considered when breastfeeding or pumped milk isn’t a workable option.

With all the potential benefits that breastfeeding may offer, it’s worth discussing your feeding options with your doctor to find what works best for you and your baby.
