It is an excellent and second to the best (squatting) position in giving birth. I had researched natural birthing after watching Business of Being Born by Ricki Lake. It is an excellent documentary on how it has become a business and the mothers needs are secondary to what the hospitals rules and policies are.
I gave birth to my son in water doing hypno babies and had a wonderful experience. If your daughter can, she should try and get these books or borrow it from library, since they do carry most of them depending on the library. Ina May's Guide to Childbirth, Back Labor No More and Active Birth : The New Approach to Giving Birth Naturally, Revised Edition by Janet Balaskas. These are all excellent books esp for those wanting to do it naturally with tons of information.
Also, having a doula really helps! I had one who was a friend and she encouraged and supported me all the way, which also made a huge difference in having a positive birth experience. It is good to be informed in all the good natural birthing positions. Standing may or may not work out for your daughter, so knowing other positions during labor, helps.
Hope this helps =)
