Many parents complain and have headaches: Why does your baby often have a fever? And when they have a fever, they run to the hospital, and even get so nervous that they ask for an injection (infusion). So, why do babies have fever so often? Parents will also find that when babies are small, especially within three years old, they often go to the hospital because of fever, for which they take medication, injections, infusions, and even hospitalization, after the age of three is much better, after the age of six to school, less sick, parents and doctors deal with less, “acquaintances” also become rusty. Why? There are two reasons for this: 1. Poor resistance Throughout a person’s life, resistance is low at both ends: low resistance in children, and as age increases, it basically reaches the adult level around the age of 6. The resistance of the elderly gradually declines. So children often have fever due to improper care, improper diet and many other factors that cause infection. Improper treatment and incomplete treatment can also lead to recurrent fever in children. If parents do not add supplementary food in a timely manner or unreasonably, children with partial or anorexic diet can affect resistance and increase the chance of infection. A little sickness on the injection, infusion, the body’s immune system is not exercised, will also lead to low resistance. 2, the organism is sick “warning” The same “small cold”, older children, adults why rarely fever? That is because children under 6 years old cannot tell adults exactly where they are not feeling well, especially babies under 3 years old, and the body can only draw the attention of the family by sending out the signal of sickness “fever”. Just like a child crying: there are many reasons for crying, it could be hunger, cold, abdominal pain, headache, “crying” is a signal to alert parents. There are many reasons for fever, and a fever reminds you to pay attention to your baby, maybe a cold, maybe enteritis, encephalitis? It may be an alarm of a major illness or a tip of a minor illness, so pay attention to him, don’t ignore it, don’t neglect it, don’t make a fuss, and don’t be careless, especially for babies within one year old, the younger they are, the more attention they should pay, especially if they are in a bad mental state and eating poorly. It is important to go to the hospital in time to find out the specific cause of the fever.
