That might be it OP :). I had previous miscarriages too, and it definately shaped my feelings during pregnancy. I was preparing myself for the worst, which translates to many negative thoughts and detachment from baby.
But once baby was born, my god, reality hit that pregnancy worked out... and my god the fish of love was overwhelming.
Believe me what you feel during pregnancy won’t be the same as what you feel towards the baby once reality hits. Right now you are relying on your imagination, your previous experiences as a child and so on.
When baby comes, that vulnerable thing just puts some magic into you.. that little princess will paint a whole new reality of what it’s like to be a mother of a girl.
I must admit I never wanted a girl. I was too scared because I didn’t know how it’s like to raise a girl. Until I got pregnant with a girl and lost the pregnancy. I was so very upset I decided I so badly loved that child. I realised the challenges I faced as being raised as an only daughter painted how I wished for a boy instead..
Then I decided I’m gonna think of it another way. That little girl is my empowerment. She is my little angel who is going to be the change I want to see in this world. I will make her feel cherished and loved for who she is, and now what society wants her to be. I will make her confident with who she is and what she achieves, and not with how she looks and so on..
Then I realised, my perception of why I initially didn’t want a girl was because I was assuming I was going to fail her along with society.. but when I dug up some passion I realised this doesn’t need to be true. I will parent my girl as a human being just like how I would a boy. I would celebrate her, her achievement... and we will have so many things to do together.
So yeh, what you are feeling is so normal OP. You aren’t horrible. You will love her. And she will love you. But you can help dig deep and challenge your expectations of parenting a girl and see where it’s coming from and tackle it.
