I have 2 stories to share.
Firstly, my aunt gave birth to her second child and refused
to bring him home from hospital (it was in another country). She had severe depression.
My grandmother stepped in - and looked after the baby for the first 3 months of his life. Then, my aunt felt she could manage (she was married but her husband was a slight waste of space) and they had a lovely relationship in the end. My cousin never blamed his mother for what she did - and understood.
Second story - in the last few years, a friend gave birth. She abandoned her child at the hospital, too (there
were some medical issues) but a week later, her child came home to her.
You are not the first to experience utter denial and shock about a birth/baby. I suspect more people than we realise really struggle...but they take the baby home and "cope" because they have a great support network. The more people you can share the truth of your circumstances with, the more you will be able to get support.
So happy to read that you feel as though you might be able to cope after all - even though it will be a struggle at times, I am sure. You are a coper, you are a great Mum and, from what I have read, I think you will be able to do this.
Please post tomorrow and let us know whether you managed to see your baby.
