Snoring is a relatively common physiological phenomenon, and snoring does not only occur in adults, but also in children. Parents should pay attention to children sleep snoring, because in general children sleep without snoring, sleep snoring may be tonsillar hypertrophy, adenoid hypertrophy, etc. 1. Occasional snoring (1) If the snoring is only occasional, it may be caused by improper sleeping posture. If the baby often sleeps on his back, it is easy to cause the tongue root to fall back, causing the narrowing of the pharyngeal cavity and causing snoring. If the snoring is caused by improper sleeping posture, you can take the side lying position to sleep. Compared with the supine position, the lateral position can reduce the backward fall of the tongue root and reduce the snoring symptoms. (2) It may be caused by milk blockage: the baby’s digestive system is not yet well developed, and parents may not burp the milk after feeding the child and let the child lie flat to sleep. At this point, milk can easily accumulate in the child’s throat, forming milk clots, which in turn can cause the child to snore. Changing the child’s position at this time will quickly correct the child’s snoring. After feeding your child, you should give your child a burp and then go to sleep to effectively prevent milk clots from accumulating in your child. (3) pillow height problem pillow height is not suitable, also will make the neck overflexed, resulting in airway is not open. If your child continues to snore, it is best to ask your doctor to check if the snoring is caused by rhinitis, sinusitis, tonsils, adenoids, or any other cause. If a doctor suspects adenoid hypertrophy in a child, an electronic nasopharyngoscopy is required. The adenoids grow at the back end of the nasal cavity and cannot be seen directly, but can only be seen with a soft endoscope placed in the nasopharynx. Not all enlarged tonsils and adenoids require surgery, but surgery or not is determined by an otolaryngologist. If adenoids and tonsils are diagnosed and cause severe hypoxia in children, the best solution is to surgically remove the enlarged adenoids and tonsils.
