Get some parachoc from the chemist. Use it daily and it will help heaps as it softens it all up and then when she's been passing soft ones for a while she'll hopefully forget about the pain. It might be a good idea to get her checked by the DR to rule out a small tear or fissure too, but they'll probably just tell you to get parachoc anyway so try that first

I've used suppositories on my boy when I've had to but unless you can get her to lay still and hold it in there for a while, it won't do much good because it will probably fall out pretty much straight away.
