I'm so glad I found this thread today. After 13 cycles of fresh & frozen IVF cycles I got my little miracle daughter and I love her to bits. I always said that I would be happy to have just one and I am but when I see her interacting with other children and running to play with them it breaks my heart that she doesn't have a sybling. When she was conceived we had no eggs left so have not gone back for another cycle although we have tried naturally without success (I have unexplained infertility). I just don't know how to stop that feeling of longing for another DD or DS even though mentally I know I'm getting older and should stop trying. I also feel I'm being selfish because I got what I wanted and want more while others are still struggling for just one.
