My son is now 11 at high school and soils himself he's on movicol which works I can get him to use the toilet at home but when at school he won't use there toilets an soils himself although it may not be like a full bowel movement he has change of clothes if this happen I meet with the school at end of each term I know he has bad days but this school seems to think take your meds an it will be sorted but from what I've read on other sites it takes a long time
