Spring is certainly a good season when everything comes back to life, however, it is also a high season for many diseases, such as influenza, epidemic meningitis, mumps, whooping cough, hand, foot and mouth disease, measles, rubella and rotavirus enteritis; there are also many diseases that tend to recur in spring. For example, allergic rhinitis and asthma are more common. At the same time, because of the climate change in spring, children do not easily adapt to it and are prone to respiratory infections, indigestion and diarrhea. Therefore, parents should pay attention to the following points: 1, less crowded confined places: spring is the season of infectious diseases, upper respiratory infections, and infants and young children’s own immune system is not yet well developed, resistance is poor. Therefore, for infants and toddlers aged 0-3 years, they should avoid going to confined public places where crowds gather as much as possible. Parents can open the windows before going to work and close them again when they return, preferably at least twice a day for 20-40 minutes each time. 2, less exposure to pollen: spring all kinds of flowers are blooming, pollen in the air, easy to trigger asthma and other diseases, so children with allergies should try to stay away from flowers, to avoid triggering asthma. 3, to improve the cold air regulation function: spring morning and evening temperature difference is relatively large, some parents like to let children wear a lot of clothes, while the children’s activity is relatively large, sweating, but easy to catch a cold, so parents need to give children diligent addition of clothes, diligent undressing in addition to the root of the problem is to help children improve their own regulation function for cold air. Take your child outdoors often. If you are afraid of the wind chill, you can at least hold him on the balcony for a few minutes; for babies born two months or more, it is best to spend an hour outdoors every day; as they get older, this can be increased to two hours (once in the morning and once in the afternoon). However, it is important to note that the best place to go for activities is a green neighborhood or park, rather than a crowded supermarket or a roadside with many cars. Young children are exposed to cold air through their skin and exhale cold air through their nose, so they can exercise their body’s ability to regulate cold air from a young age, thus achieving the effect of strengthening their physical fitness. From autumn until winter, let children try to wash their hands and faces with cold water and drink cold water, so as to enhance their ability to adapt to the cold. More exercise, more exercise, a balanced diet, to pay attention to dietary hygiene, such as washing hands with soap and running water before eating. 4, appropriate calcium supplementation: spring children grow and develop faster, more active, especially in the north, young children under 3 years old, due to the lack of sunlight throughout the winter, spring will often appear due to calcium deficiency and leg pain, therefore, the spring to give children appropriate calcium supplementation is also very necessary. 5, pay attention to prevent indigestion in young children: spring young children often appear diarrhea and other cases of indigestion. Indigestion is caused by a variety of reasons, mostly due to improper diet or germ infections. For infants and toddlers, food should be as tasty and light as possible, suitable for the child’s digestive and absorption capacity, do not eat food that can easily cause allergies, and pay more attention to dietary hygiene. In addition, the digestive enzymes of the gastrointestinal tract of young children are not enough, so they can also be supplemented with some digestive enzymes to help him digest, or Chinese medicine to regulate.
