From a baby’s diet, clothing, to sleeping arrangements, new mothers have a lot to keep in mind. One such aspect that they often overthink about is choosing the right milk. Is formula milk or breast milk better for an infant? This World Breastfeeding Week, we will answer this query for you.

To understand this better, we reached out to Dr Khushboo Saxena, Senior Consultant, Obstetrics and Gynaecology, ShardaCare-HealthCity, Greater Noida.

Breast Milk vs Formula: Which Is Right for Your Baby?

Dr Saxena says that breast milk is nature’s perfect food for babies. On this note, the expert lists its benefits:

  • Beyond delivering ideal nutrition, human milk is ‘living’ food packed with antibodies, helpful bacteria, and natural hormones.
  • It protects infants from illnesses and fuels healthy brain and body development.
  • Babies who receive breast milk have built-in protection against everyday infections such as ear aches and tummy bugs.
  • It also provides protection from long-term risks driven by conditions such as allergies, diabetes, and childhood obesity. 

“Mothers benefit too; breastfeeding speeds up physical recovery after birth and offers long-term protection against breast and ovarian cancers,” adds Dr Saxena.

What about formula milk? The expert explains, “If breastfeeding isn't possible, isn't enough, or simply not the right choice for your family, high-quality infant formula provides safe, complete nutrition. While formula cannot duplicate the unique immune-boosting cells found only in breast milk, it ensures your baby gets the essential nourishment they need to thrive. Health experts encourage exclusive breastfeeding for the first six months, continuing alongside solid foods up to two years or beyond.”

Health Benefits of Breast Milk 

Speaking about some of the health benefits of breast milk, Dr Saxena lists down the following:

  • Builds a stronger immune system, which means fewer ear, chest, and stomach infections in childhood.
  • Lowers the risk of allergies, eczema, obesity, type 1 and type 2 diabetes, high blood pressure, and heart disease later in life.
  • The close skin-to-skin contact during feeding strengthens emotional bonding and supports better social development.
  • Breastfeeding offers protection to the mother. The longer the total duration, the lower the risk of breast cancer and ovarian cancer.
  • In mothers, It also reduces the risk of type 2 diabetes, especially for women who had gestational diabetes, along with lower risks of high blood pressure, heart and endometrial cancer.
  • It helps moms return to their pre-pregnancy weight faster and can provide natural birth spacing in the first 6 months if exclusively breastfeeding.

Does Formula Milk Have Any Side Effects?

According to a report by the World Health Organization (WHO), formula milk is an expensive and inferior substitute to breast milk that fails to provide the best conditions for a baby's natural growth and development. The study highlights that aggressive marketing by the formula milk industry has a negative effect on infant health. This is because it discourages breastfeeding. 

When infants are fed formula milk instead of being breastfed, they miss out on important health benefits. Specifically, depending on formula milk raises a child's risk of struggling with obesity and developing other non-communicable diseases later in life. To summarise, the report warns that promoting the overconsumption of these formula products can actively undermine a child's health and violates their basic human rights.

In fact, formula milk may increase the long-term risk of various illnesses. By understanding these crucial differences and consulting a doctor, you can choose a flexible feeding approach that ensures your baby gets the essential nourishment.
