Children with a healthy immune system is an important foundation for good health, creating momentum for outstanding physical and mental growth and development. To build a solid foundation for the baby's immune system, parents need to care for, monitor, and care for the baby from the time the baby is in the womb until birth, growth, and adulthood. This is a long, persistent process that takes a lot of effort and time as well as the parents' search for useful information.

The immune system plays a very important role in human health, especially in children. Strengthening the immune system will help children overcome the risk of disease and help the body develop completely.

Many parents often complain that their children get sick more often from the time they start eating solid foods until about 3 years old, without knowing the cause. Doctors have given the answer to this problem because this is the period known as the “immune gap” when the child’s immune system is not fully developed, making the child very susceptible to disease due to lack of immunity. So when will the child’s immune system be complete?

Children are susceptible to chronic and persistent infections, which are often a characteristic sign of a weakened immune system. When a child's immune system is weakened, the body's protective barrier against pathogens will be significantly affected, making the child's resistance not as good as before.
