Pedia-Lax and Fletcher's are pediatric stool softener brands that are appropriate for children. Pedia-Lax stool softener comes in a variety of fruit flavors, and Fletcher's tastes like root beer. Neither brand requires a prescription, and both brands are available at Amazon.com, as of December 2015.
Pedia-Lax softens stools with ducosate sodium, and Fletcher's softens stool with senna. Liquid stool softeners are generally safe for kids, but use of stool softeners should be supervised by a pediatrician, says WebMD.
Over-the-counter liquid stool softeners are given to kids to clear constipated bowels. A high-fiber diet rich in fruits and vegetables is recommended to prevent constipation in children. Probiotic foods such as yogurt promote digestive health and help to prevent constipation, according to WebMD.
