Not every unexpected pregnancy will result in a child that is unloved and resented. I really hate this assumption. My first two were unplanned and abortion wasn't an option for me due to my beliefs. I was devastated, as was my (now) husband, but we both love our children more than anything, by the end of each of my pregnancies, I loved them more than words can describe, despite being horrified and scared when I had initially found out (and my husband begging me to terminate). I am thankful every day that I was brought up against abortion, because had I not been, I would've terminated, and missed out on two of the most beautiful precious things in my life.
Then theres the expectation that a child with DS and similar will be terminated. There is less and less support for people to continue with these pregnancies because of the 'cost' to the community, when its so easy to discontinue the pregnancy.
Not to mention the number of girls and women who are coerced into abortion by their partners/mothers. It really upsets me. I just don't think more relaxed laws is helping women at all.
