Could this be true?

Sorry to come to you with this kind of question,but I do trust you so....A person who is saying that he is knowlegeble in Bazi and feng-sui told me two yaer ago that if i will chose 2 have children before age of 30,so born before year of 2009,it will be harmfool,no good for me.So he advised me to have my children no earlyer of 2009.I do have a sun born in the yaer of the dog fire,2006,that I am very happy with him becausethis far suchhe is healthyand easygoing,calm and with a very happy disposition.But i read that a child born in the Fire Pig would also be good for me because I am born in the year of earth goat,1979,26 of september,10am,snake hour,......and pigandgoat are very good friend and love each ther.So.....my question:do you think that would be good for me to have a baby this year or.....better to wait till I will be 30?I do hope that my question will have some sense and not to seem foolish.
