5 year old bedwetting, little stamina, sensitive emotions

When I was a child I was a bedwetter, with not much stamina and very emotionally sensitive. I wet the bed until age 16 or 17. My father also wet the bed when he was a child. My son, now 5 years old, has auburn hair, fair skin, weighs 23 kilos. He wears a diaper every night to bed which is usually very wet in the morning. I was a deep sleeper as a child and I think my son is a deep sleeper. I can't say at what time of the night he wets his bed. He does regularly wet the bed when he takes a daytime nap. He is also very sensitive to scary images on television and to mean children. He will have anxiety about sleeping and have nightmares after seeing these images. He tires easily when playing sports, but not when playing on playground equipment. He is fearful of the dark, particularly right before bed so my wife or I lay down with him until he is asleep. Would you be kind enough to suggest homeopathic treatment for him? Thank you. Chris
