Sneezing and runny nose in infants can be self-cured if it is caused by cold; if it is caused by allergy, it is more difficult to be self-cured in most cases. Sometimes when the air conditioner is turned on or there is sudden cold air, small infants can also sneeze and have a runny nose, which may be self-cured after the external environment is lifted. If a child has a fever with a runny nose and sneezing, it is due to an upper respiratory tract infection. As the cold improves, the runny nose and sneezing will be reduced to varying degrees, and eventually improve completely. If the runny nose and sneezing is caused by allergy, it is more difficult to cure by itself in most cases, and medication will usually be given to relieve the child’s symptoms of runny nose, sneezing and nasal congestion, so that the baby can drink milk and sleep normally. If the rhinitis is not treated in time, the nasal congestion affects the baby’s sleep at the same time, it will also affect the baby’s eating. Babies sneezing should pay attention to keep warm so as not to catch cold, pay attention to keep the room temperature suitable. Drink plenty of warm boiled water to help the body metabolize and promote detoxification. Due to the low immunity of infants, avoid contact with people with fever and cold. You can give your baby appropriate vitamin supplements to improve their immunity.
