I am not going to say something comforting.
From what I read about 胎教 in this few months, I am sorry to say, the bb knows her mom hate her already. and, she will hates her mom after giving birth (if there is still a chance).
What a poor little soul! But things can be changed if she feel loved again.
songmei, no matter what is the final decision, some damage will never be mended (for all of you).
