I have never administered it, but I had some for me back in May when I was in the hospital. I was so backed up that I was vomiting & thought I would die from the pain. It really was a waste of time for me. It didnt even begin to reach the problem. I ended up drinking a solution (similiar to Mirilax) twice a day & little by little it eased. The xrays showed I was so impacted that the doctors couldnt believe I didnt have problems sooner. I guess I just always had enough of a bowl movement to keep it "just" at bay! As far as hurting your daughter, I dont think you will do that. If you take your time & read the directions carefully. It might be unformfotable (hell....it definitely will be) & she probably will give you a hard time, but keeping her still & going slow & easy is the key. Good Luck!
