When a child loses bladder control while sleeping and wets the bed, it is often due to the same cause that causes some adults to wake up twice or three times a night to use the restroom—adrenal fatigue, because the adrenals help to regulate fluid balance in the body. It can also be caused by fear, hypoglycemia, mineral imbalances, or kidney and bladder weakness. If the child also tends to wet themselves during the day, they may have a urinary tract infection.

Mineral imbalances may also contribute to this problem. Magnesium deficiency in particular may be a root cause.

Kidney herbs (cornsilk, JP-X, Kidney Activator, marshmallow, parsley) are often used to encourage urination during the day. If the problem is a lack of tone in the sphincter of the bladder then uva ursi taken as a tea may be helpful.
