I am unsure if I should but my baby's father last name as my child's... he left me when I was a month pg and I haven't seen him since and he wants me to put the child's last name as his and I am scard that if I don't he will take the baby from me . Is there any way he could do that even if we are unmarried... is the a way he could fight me to put his last name in the place of mine
