Laryngitis in babies usually recovers in about 1 week, depending on their age, severity and whether there are secondary infections. Pediatric laryngitis is one of the common respiratory diseases in pediatrics. It is usually acute in the first 3 days and is serious, requiring timely anti-infective treatment to reduce laryngeal edema and keep breathing open. If there is no secondary bronchitis or pneumonia, recovery is usually possible in 3-5 days; if there is secondary bronchitis, it may last about 7-10 days; if there is secondary pneumonia, treatment takes longer and may last 10-15 days. Laryngitis in children is often aggravated during sleep and at night, and in severe cases it can lead to breathing difficulties and even asphyxia. Therefore, it is necessary to ensure that the child is attended to at night or during sleep, and if there is any abnormality, he should go to the pediatric department for diagnosis and treatment in a timely manner, and closely observe the changes in his condition, and give active anti-infection treatment in a timely manner if there is aggravation or secondary diseases. It is recommended that the child get enough sleep during the illness, avoid crying, and avoid spicy and stimulating foods, and eat a light and balanced diet with plenty of fresh fruits and vegetables.
