When my wife was pregnant, I told everyone I had no preference. That was mostly true, but privately I desperately wanted a daughter. When the doctor said we were having a boy, I smiled and celebrated, then felt disappointed for about a day.
My son is nine now, and I cannot imagine wanting anyone else. I feel guilty even writing this because if he ever read it, he might think he wasn't wanted. He was wanted. I just had an imaginary child in my head before I met the real one.
