This can be a bit more difficult,as we all know,children's stool softener takes it's time to work,right now,I would say to try small amounts of a mild one and check on the timing to set her to go in the afternoon,once she starts going regularly stop the meds and we will hope for the best.
This is all I can think of at the moment,If I come up with an easier way,I will be sure to let you know ASAP.
