Trying for a girl

Ok ladies (and maybe gents!)
​My hubby already has two wonderful little boys from past relationship and he is dying for a little girl. I don't really care what we have as long as we have something healthy, but I am curious to hear opinions. 
​I have read a lot about "how to get pregnant with a X!" And I want to hear other people's stories. Does the witch doctor mumbo jumbo (eat sweets and fruit, have shallow sex, have sex 2 days b4 O, ect......) ever actually work? Has anyone ever successfully planned a pregnancy this way?
