Treatments for childhood constipation
usually includes stool softeners and changing the child to a less constipating diet, with more fiber and fluids.
Good choices of fluids include apple and prune juice and perhaps switching children low-fat milk or soy milk.
The type of laxative depends on the age of the child and the exact problem. You may need to make an appointment with a doctor.
Wishing you good health.
