My granddaughter aged 5 years has highly swollen adenoids and tonsil for last couple of months. She is generally a healthy child with no problems at all during the day, very intelligent and energetic - always 5 steps ahead in her school. However, at night she suffers from nasal blockage and breaths through her mouth, and at times momentary pauses in breathing during sleep. She is slim and has a tendency to catch cold. What homeopathic medicines do you suggest?
