BabyCupid, I also heard the same. c-section then not accurate.. only natural births then can be counted. also, some masters refuse to give very good timings of birth, or very good bb names.. cos if the bb's natural fate cannot "match" the auspicious timings/names, the bb may die early, parents may be unlucky or die early, or the bb may have alot of health problems later in life. but actually, every parent also wants the best for their child. if they have the $ and the knowledge, they will want the best, including the best timing of birth and the best name. Just to share, my uncle is very into this .. really. no joke. all his 3 kids' time of birth was calculated by him. names also given by him. but in the end, very unfortunate lives..
