Infants have stronger immune systems than most people realize. Immediately after leaving the womb, newborns have immune defenses that protect them against the barrage of microbes they are suddenly exposed to. However, as babies’ bodies adapt to the world, their immune systems evolve and strengthen. As a parent, you play one of the biggest roles in supporting your newborn’s immune system during this stage.
Prioritize Breastfeeding if You’re Able
Breast milk is called liquid gold for a good reason! Better immune function is one of the many long-term benefits of breastfeeding for infants. It’s packed with essential nutrients, antibodies, and immune-boosting compounds, so it strengthens your baby’s health and defenses.
Colostrum, the thick, yellow milk produced in the first few days postpartum, is exceptionally rich in immune factors. It helps your baby fight infections, especially in those early days when they are most vulnerable.
If you’re unable to breastfeed, don’t worry. Baby formula is fortified with important nutrients to assist in healthy growth. Though it’s true that formula’s immunity benefits are lower, you can certainly support your baby in other ways.
Keep Vaccines on Schedule
Vaccinations are some of the most effective tools for strengthening your baby’s immune responses. They help your baby’s immune system recognize and fight off dangerous illnesses like polio, whooping cough, and measles. Getting your baby vaccinated is an invaluable step toward their long-term health.
Offer Plenty of Skin-to-Skin Contact
You might be surprised to learn that cuddles do more than bond you to your baby. Skin-to-skin contact helps to regulate your newborn’s body temperature, breathing, heart rate, and stress. Moreover, it transfers beneficial bacteria from your skin to your baby’s, naturally building their immunity.
Keep Their Environment Clean but Not Sterile
A key part of making your home safe for your infant is keeping it clean. That said, a little exposure to microbes is necessary for your “teaching” your baby’s immune system to respond to the environment. Over-sanitizing everything might slow your baby’s immune development.
Fortunately, it’s nearly impossible to maintain a sterile home environment. You would have to be cleaning all day every day, and no one has that time—especially not new parents! Instead of worrying about cleaning too much, focus on cleaning the counters and floors every day and developing good handwashing habits.
Ensure They Get Enough Sleep
Sleep bolsters the immune system. During sleep, your newborn’s body strengthens its defenses and grows. Newborns need 14–17 hours of sleep daily. You can help by keeping your baby comfy at night and establishing a gentle sleep routine.
The Takeaway
Supporting your newborn’s immune system is one of the best things you can do to give them a healthy future. With these pointers, you can foster a balanced, healthy environment to help them thrive. Every small step you take now will help your little one grow strong, healthy, and ready to explore the world.
