Don't know how many times I've been asked that already, and we're just 5 months into this. We did use a fertility doctor but twins also run in my wife's family so I usually just say that to avoid any further awkwardness.We were always asked if they were conceived naturally, if twins ran in our family, or assisted methods. We were always polite but never understood why people wanted to know. I always thought that would be like me asking parents of a single kid if the pregnancy was via doggie or missionary.
