My very best wishes to you and your family, OP.
I agree with those who say that others should be quiet about gender, and not project their own wierd ideas on anyone else.
I also totally agree that one should count one's blessings, and welcome every child s the unique individual that they are, to be loved and to love in return.
However, if in one's heart of hearts, there is some sort of longing for one or the other, born out of positive or negative experiences, then it is wise to admit it, just to oneself.
Having worked as a midwife, and brought up in a family that treated boys and girls equally, I thought that I had no especial wish. But I felt a yearning when the last boy was born - not a negative wish, but just a slight sense. One night, in those hazy first days, I dreamed of my daughter, of saying ' I'd have loved to have met you, but it wasn't to be in this lifetime'. I am usually such a practical and down-to-earth (NO new-agey, dreamworld nonsense!)person that it took me by surprise, but I held that dream, cherished it and loved my sons with all my heart and strength.
Now I have wonderful nieces, daughters-in-law, and 2 grandsons whom I cherish, and have no idea as to whether a grand-daughter will be born in this lifetime. But I do occasionally have a sense of her, looking very like my mother.
