You have been doing your best. Still if you can apply little Ayurveda wisdom, not widely known, these would support your efforts to prevent bedwetting by the child. Please give her roasted groundnuts and seasame seeds to chew and eat. These are harmless oil seeds used for food. Moreover tab Mentat of Himalaya may also be used. These things are harmless and for prolonged use esp in winter. Triphala and black bitumen containing medicines also help. Counselling and rewarding the child for dry bed in the night also helps to make child wilful and strong in thought to control bedwetting. For any further query or advise, pl write direct question or meet any Ayurveda doctor near you. In my clinical ayurveda of three decades I have seen many children benefitting. Hope it helps.
