My brother complains of his son still bedwetting even at the age of 6. Well, bedwetting is common among young children. Most will outgrow the problem by age 6 to 8 as their bladders grow larger and bladder control improves. Bed wetting is rarely caused by urinary tract infection or emotional problems.
So, I told my brother to limit the child drinks during the two hours before bedtime and to remind the child to get up during the night to urinate. It may help to provide a bedside potty chair and night light may help. I also told him to reward the child for dry nights.
