Well right now I have 3 girls and 2 boys so depending on what we have I may choose the sex next time. Certain doctors specialize in sex selection and choosing the amount of kids you want. They take her egg and your sperm and fertilize them and implant them into the womb. It's a quick way to speed up the process. Some people don't believe in it but I do.         Congratulations on the twins! :clink    WHAT!! I am confused why would you want to pick the sex? And what do you mean have twins set for us by a doctor on the next run. Just a little confused.
