Some I know seem to live by this calendar, and believe it really can predict the gender of your baby - - depending on your age, the month of conception, and the birth month. Others have believed in it in the past, but it has failed them recently. I don't know how much it really is true, but here is a link to one. I've also heard that douching with a vinegar or baking soda douche can encourage the gender of a new baby - vinegar for a girl, and baking soda for a boy. I would like to try out these ideas, but will lean on the allmighty God for what He wants for me. My husband REALLY wants a baby boy in our future, and we currently have a total of 3 girls (one 13 year old daughter is his by an earlier marriage, and we have a 3 year-old and 15 month old as well). We want to try everything that's out there, but God will decide in the end, won't he?
