Yes, I am personally. But that means nothing, listen.
Your talking about the life of something that DOESNT exist yet, it is PART of a woman. Its her body that is going to change, and HER who will go through god knows how many hours of labour, sorry but in my opinion guys dont have much say over this.
If the mum wants to have it, good for her, I hope she is ready.
If she doesnt her choice as well, its her body and her life, not someone else.
