Allergic dermatitis is a common disease of many babies, especially in spring and winter. What should a three-and-a-half-year-old baby do if he gets allergic rhinitis? Let's have a look.

First, what should my baby do with allergic rhinitis at the age of three and a half?

1, if your baby has allergic rhinitis, you should pay attention to balance your baby's diet nutrition, especially in dry autumn, so you should eat more fresh fruits and vegetables at this time and avoid eating some seafood or cold-irritating food, because many foods may induce your baby's rhinitis attack. Try not to take your baby to play in parks with more flowers and plants, because pollen can easily lead to your baby's rhinitis attack.

In addition, parents should pay attention to keep their baby warm. If the weather is cold, they should add clothes to the baby in time. In addition, when the weather is cold, they try not to take the baby out, which can effectively avoid the cold air from causing certain irritation to the baby's nasal mucosa. In addition, it is best for the baby to wear a mask when going out, so as not to expose the baby's nasal cavity to allergens. After the baby comes back from going out, it is necessary to clean the nasal cavity and change clothes in time, which can also prevent the baby from having rhinitis attacks.

Second, what are the reasons for baby allergic rhinitis?

Many babies with allergic rhinitis are due to genetic factors. If one of the baby's parents suffers from allergic rhinitis, the probability of allergic rhinitis after the baby is born can reach 50%. If both parents suffer from allergic rhinitis, the probability of having allergic rhinitis after birth will be as high as 75%. Some babies suffer from allergic rhinitis because of their usual diet, such as fish, shrimp, milk and eggs. Because some allergens in some foods can easily stimulate the baby's nasal mucosa, which will lead to allergic rhinitis in the baby.
