Cradle cap, or seborrheic dermatitis, is most common in babies around 3 months of age, but it can last for a year or longer. Most cases of cradle cap disappear by the time a baby is 1 year old, but some cases can last until the age of 4. Cradle cap in babies is a harmless condition. Parents can help their children get rid of it with a few simple steps.

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.
