Hi, I've got several books on the subject of home-health and doctor's home remedies, and all of them say that nobody should take laxatives of any sort on a regular basis. It forces the body to not want to.....do its duty...on its own. I don't have time for a longer reply at the moment, but I would contact a nutritionist or some other professional who could offer you a whole list of foods which help the digestive system work better - prunes, etc. As I say that, I also heard that some children/adults with allergies to milk and dairy products have troubles with their digestive system. Your son should be checked for that. It could be the food he is eating which is causing the constipation.
