Good sleep is a prerequisite for children’s healthy growth and development, and children’s sleep disorders are receiving more and more attention from the medical profession and parents. Among the many diseases that cause sleep disorders in children, snoring in children is the most common and has the most far-reaching impact. If your baby snores only occasionally during sleep, it may be caused by improper sleeping position. You can change the following sleeping positions for your child, you can let your baby sleep on his/her side, and the side position can reduce the backward fall of the tongue root and alleviate the snoring symptom compared with the supine position. Besides, parents should also pay attention to whether the height of the pillow is appropriate or not, if the height of the pillow is not appropriate, it will also make the neck overly flexed, resulting in poor airway. Overly obese children will also appear to sleep snoring, baby oropharyngeal fat pad thickening, due to gravity, sleep throat and tongue space becomes narrow, fat pad accumulation aggravates the airway space becomes narrow, easy to cause snoring. If obese children can be reduced to standard weight, it can improve the state of low oxygen during sleep and reduce the occurrence of snoring during sleep. If the above reasons are excluded and the baby still snores for a long time, it is considered to be a pathological condition and you need to take your child to the hospital for medical checkup. Snoring may be caused by the following reasons: (1) adenoid hypertrophy: adenoid is a larger piece of lymphatic tissue located at the top and back of the nasopharyngeal cavity, and proliferates most vigorously at the age of 3-6 years. Normal proliferative bodies do not have any effect on children, but if the adenoids are too enlarged and block the posterior nostrils, so that the air in and out of the nasal cavity is blocked, and after children fall asleep, the gas exhaled from the trachea is forced to be exhaled from the mouth, and the gas impacts on the root of the tongue and other tissues from time to time, giving out a snoring sound. If adenoid hypertrophy causes children to sleep poorly and snore at night, it is recommended to go to the ENT department for examination, either by rhinoscopy or CT examination of the lateral nasopharynx and nasopharynx. If the compression of the airway is more than 2/3, it should be treated surgically, otherwise it will affect the normal growth and development of the child. (2) Enlarged tonsils: Normally the tonsils, which grow on both sides of the pharynx, have the function of defense and resistance to the invasion of external germs. However, some children’s tonsils are too enlarged, so that the two sides of the tonsils almost touch each other, blocking the pharyngeal cavity, resulting in poor breathing, due to the lungs, the trachea can not be exhaled from the nasal cavity smoothly exhaled, a sleep will be open-mouth breathing, snoring. If tonsil hypertrophy is more than 2 degrees, the symptoms of snoring will appear, and if it is more than 3 degrees with obvious sleep breathing disorder, it can be treated surgically. (3) Deviated nasal septum: Sometimes the nasal septum (the bone that separates the two nostrils) is pushed to one side, blocking the airflow through the nostrils. As a compensation, the child will inhale more air through the unblocked side of the nostril, thus making noise. Surgical correction is the only treatment for a deviated septum.
