Understanding Bed-Wetting Issues
Even though your kid is obviously fully toilet-trained by now, there may be cases where your child is wetting his bed at night. This is a very sensitive issue, and you need to be quite careful in handling it.
After a certain age, bed-wetting is naturally a huge embarrassment for your child. So do not make a huge fuss about it, or scold him, or make him feel ashamed of what he has done. Always remember that bed-wetting has a reason behind it, which you need to discover.
Talk to your child and try to discern the problem. Find out if he is under stress or whether there is anything wrong at school. There may even be something at home that is troubling him. Make him feel comfortable and address the issue with patience.
