The book builds up a case for active birth very well. It avoids unresearched comments about "conventional" births so that its arguments for active birth stand on their own with no need to critsise or condemn other methods.
It offers information, support and intelligent advice and guidance - something I have found lacking elsewhere. It has given me the confidence to proceed with the home birth of my third child and is an excellent way to inform your birth helpers as to what you want to achieve.
The appraoch makes sense physically as well as emotionally and makes its points quietly and without sensational claims for it being the only way. This I respect and therefore accept the concept more readily.
Finally, it is refreshing to read a book around birth that clearly considers its readers to be able to make their own minds up based on good facts and well laid out information.
