If it does not get better for a long time, it will affect the ventilation and drainage of the nasal cavity, resulting in the accumulation of secretions, so this does not mean that the baby will soon be well. Sticky nasal mucus can use wet towel hot compresses on the nose, can relieve the symptoms of nasal congestion in babies, to timely use wet cotton swabs to clean up the baby’s pus nasal mucus, to keep the airway open. During the cold, you should give your baby more boiled water, eat more fresh vegetables and fruits, ensure that children have enough sleep, improve children’s immune system, and promote the recovery of the condition. It is recommended that babies with uncomfortable symptoms should seek medical treatment in time to avoid serious consequences.
