Bedwetting in a 5-year-old child may be caused by over-tiredness, mental factors, enuresis and other reasons. 1. Over-tiredness: If a child wets the bed once in a while, he may be over-tired from playing during the day and sleeping soundly and deeply. So sleep can not wake up, the phenomenon of bedwetting. Or eating too much liquid food before going to bed can also cause bedwetting. 2. Mental factors: if the child just recently repeated bedwetting, may be recently frightened or emotional tension, sadness, anxiety and so on, can cause the child bedwetting. 3. Enuresis: Due to congenital spina bifida or immature brain development, the child suffers from enuresis, so bedwetting occurs. If a 5-year-old child wets the bed every day, he should go to the hospital in time and follow the doctor’s instructions for treatment. For children who occasionally wet the bed, parents should insist on doing urinary training for the child, in the night regularly wake up to urinate. You can’t blame the child for bedwetting, it’s a serious psychological blow to the child.
