My son is 6 and he hasn't been officially diagnosed with spd but we are in the process seeing how he has 110 of the characteristics one problem he has had is toileting. He has been on laxatives and miralax for over a year now and they dont work. He has been to the hospital and drs office to have big cleanouts done but he still only goes once or twice in a two week period. Does anyone else know what i can do other than the medications and diet because none of these things are working and it is soo hard on him because he constantly has stomach aches and vomiting from this. Any advice would be appreciated.
