My mum had GD with me and my 3 sisters and would always make comments to us.....If each one of us were a boy our name would be Adam.... "I never liked buying clothes for you girls so I would buy boy ones" she also buys boys clothes for my daughters. She would joke with her sister in-law about swapping their last child (she had 4 boys) and it did affect me deeply. I might add she never once reassured us that we were loved and wanted above a boy and still tells me she only ever wanted boys and was trying for one each time
I was however, a sensitive child and did take things to heart, but how can you not with that, kwim? It now also affects her relationship with her grandchildren, i can clearly see she favours her grandsons over my girls and I wonder if I would have seen it so much if I didn't know about her GD. I realize this is not what you are talking about doing as you would never make your child feel like they were not wanted but because of my experience my children will never know I longed for a boy, I don't want to risk them feeling unwanted even if it's not one bit true.
