When Do Babies Develop Immune Systems?
Babies start developing their immune systems while still in the womb, but their immune systems are not fully functional until they are about 6 months old. Before birth, babies receive some immunity from their mothers through the placenta. This immunity helps protect them from certain infections during their first few weeks of life.
Once a baby is born, they continue to receive immunity from their mother through breast milk. Breast milk contains antibodies that help protect babies from infections and illnesses. However, this passive immunity only lasts for a few months. As babies grow, their immune systems begin to produce their own antibodies and they become more resistant to infections.
What Factors Affect Babies’ Immunity?
Several factors can affect a baby’s immunity, including:
- Breastfeeding: Breastfeeding helps boost a baby’s immune system by providing them with antibodies from their mother’s milk.
- Nutrition: A well-balanced diet is essential for a baby’s immune system to function properly.
- Hygiene: Regular hand washing and keeping your baby’s environment clean can help prevent the spread of germs.
- Vaccinations: Vaccinations can help protect babies from serious illnesses and diseases.
- Genetics: Some babies may be born with weaker immune systems due to genetics.
How Can You Boost Your Baby’s Immune System?
While you can’t completely prevent your baby from getting sick, there are several things you can do to help boost their immune system:
- Breastfeed: Breastfeeding provides your baby with antibodies that help protect them from infections and illnesses.
- Provide a well-balanced diet: A healthy diet that includes fruits, vegetables, and protein can help strengthen your baby’s immune system.
- Keep your baby’s environment clean: Regularly washing toys and surfaces can help prevent the spread of germs.
- Get vaccinations: Vaccinations can help protect your baby from serious illnesses and diseases.
- Avoid exposing your baby to sick people: Try to keep your baby away from people who are sick, especially during their first few months of life.
