There is no magic age for determining when bedwetting is a problem. Many refer to 6-7 years of age as when a parent needs to address the problem. After this age often concerns begin to arise.
Around 70% of children stop wetting the bed at night by the time they reach 5-6 yrs of age. By around age 7-8 there are around 8-15% of children who still wet their bed. If your child is over the age of 5 ½ and is still wetting the bed at night, they may well grow out of it in time, however if your child complains about wetting the bed, feels uncomfortable about it or begins to show embarrassment or self-esteem issues, then now is the time to help your child become dry at night.
