Question

Why do children snore noisily in the middle of the night?

Answer

Based on your description, the child has adenoid hypertrophy. This issue may not be due to the adenoids becoming more enlarged in the middle of the night, but rather because the child sleeps more deeply, causing the muscles around the throat to relax and resulting in louder snoring. It is suggested that you try having the child sleep on their side to see if there is any improvement.
