Babies with a strong, balanced gut microbiome tend to show steadier immune responses, better digestion, and overall healthy growth

Breast milk does more than nourish a baby. It helps lay the foundation for their gut health. From the initial days, it introduces beneficial bacteria like Lactobacillus and Bifidobacterium, which begin shaping the infant’s gut microbiome. This balance of microbes plays a key role in both digestion and immune system development.

Breast milk also contains human milk oligosaccharides (HMOs), which are special sugars that babies don’t digest themselves. Instead, these sugars feed the good bacteria, helping them grow and create a healthy gut environment. Dr Shashank Bansal, MBBS, Consultant Pediatrician and Neonatologist, Ujala Cygnus Group of Hospitals shares all you need to know:

A stable gut microbiome does more than support digestion. It helps the immune system learn how to respond, knowing when to act and when to hold back. This early learning may lower the risk of allergies, infections, and some longer-term health concerns.

What’s also special is that breast milk changes over time. It adapts based on the baby’s age, health, and even the environment, offering support that grows with the baby.

From a clinical point of view, we often see the long-term benefits. Babies with a strong, balanced gut microbiome tend to show steadier immune responses, better digestion, and overall healthy growth. That’s why, when possible, we recommend breastfeeding as a reliable and natural way to support a baby’s development from the start.
