Infants need to be cleaned up in time due to the high level of secretion and the need to avoid adverse effects. If an infant has boogers in the nose, you can moisten the boogers by placing a small amount of water in the nasal cavity, so that the boogers can be completely softened and then gently sucked out through a nasal aspirator. Because if the boogers block the nasal cavity, it is easy to cause breathing problems, and may even lead to serious consequences. Normally, we should pay attention to breastfeeding babies on time and on demand, and if babies eat milk powder, we should pay attention to feeding more water in case babies’ nasal mucous membrane is dry and there are more boogers. In addition, the baby’s nasal mucosa is more fragile, easy to lead to nasal mucosa broken bleeding situation, so usually must give the baby good warmth. When breastfeeding, women should eat less spicy, stimulating and cold food to reduce the chances of the baby getting sick. In addition, if a baby’s boogers are too deep, it is recommended to clean them by sucking them out with a nasal aspirator. Because the boogers are deep, it is not recommended to use a nose clip in case the baby does not cooperate and cause damage to the nasal mucosa. Moreover, when the temperature changes or when the baby has fever or cold, it is easy to have boogers, parents should pay attention to clean the boogers regularly, and the operation should be gentle.
