If your baby’s throat-clearing sound at bedtime is caused by drinking too little water, it is considered normal. If it is due to congenital laryngeal stridor or cold, it is not normal. Whether or not a baby’s throat sound is normal before bedtime depends on the specific situation and cannot be generalized, as there are obvious individual differences. If your baby’s throat clearing sound before bedtime is caused by drinking too little water and having a dry throat, it is usually considered a normal phenomenon and parents do not need to worry too much. However, if the baby’s throat sound is caused by congenital laryngeal stridor or infantile cold, it is not normal. The child may also have other symptoms such as coughing and feeding difficulties. To summarize, there are many reasons why babies always make a sound like clearing the throat before bedtime, and it is necessary to go to the hospital to complete a series of tests to clarify the specific cause.
