What should four-year-old children do if they often wet the bed recently?

Children often wet the bed regularly, for example, at a certain time, usually in the middle of the night, sometimes many times a night. Treat children who wet the bed, avoid beating, cursing and humiliating punishment, which will only make children more nervous and aggravate the phenomenon of bed wetting. It is necessary to reduce the psychological burden of children and let them build confidence. Once the child does not wet the bed, praise and encouragement should be given, and the phenomenon of bed wetting will be reduced. Children have recently started to wet the bed frequently, which can be considered as the influence of cold weather.
