please don't let her sit in soiled pants all day or other punishments. this can create even more physical or psychological issues. your first step is to see he medical provider to make sure there are no medical reasons for this behavior. how would you feel if she had a urinary tract infection or diabetes or a gastrointestinal disorder? if nothing is found they you can work on behavior approaches. way different than what you are doing. your pediatrician can help or you can see a child psychologist. this problem can and will be solved but it is going to take some patience and understanding on your part and a different behavioral strategy.
my daughter is 5 literally everyday she either pees her pants or doesn't wipe after pooping or peeing help! . she always has an excuse as to why it has happened; we've tried everything from disciplaning to rewarding and from telling her that she will smell and no one will want to be around her and we've tried just letting her sit in it all day. nothing has worked and i'm at my wits end! . .
